We service Hyundai Solaris: replacing the fuel filter. Which is better, how to relieve pressure

Fuel filter for Hyundai Solaris: where is it located, price, originals, analogues, articles

The manufacturer recommends updating the fuel register every 60,000 km - every fourth service.
The interval is subject to adjustment towards reduction if the car is systematically refueled with low-quality fuel. Technical parameters of the TF: outer diameter 80.0 mm, inner diameter 62.0 mm, length 59 mm.

When to change the fuel filter on a Hyundai Solaris

According to the passport data of your car and the operating instructions for your car, the TF should be replaced every 60,000 km or every two years, depending on the situation, which comes first.

A clogged fuel filter on a Hyundai Solaris can cause a drop in engine power and, as a result, limit the speed at which the car can move. It also leads to increased emissions of toxic gases and problems starting the engine. In this case, the fuel filter must be changed regardless of the mileage of the car.

If the pressure in the fuel purification system is less than 345 kPa (3.45 kgf/cm²), then most likely the electric pump, fuel pressure regulator has failed, or the filter has become clogged.

Hyundai-Solaris fuel filter: design and principle of operation

Replacing the Kia Seed fuel filter
The filter in the fuel system is one of the most important elements, since it is the one that cleans the fuel entering the engine. It is this unit, if properly preserved and clean, that can significantly increase the service life of any motor. In many ways, this possibility is due to the fact that during operation the filter performs the following functions:

• allows you to keep the vehicle’s fuel system in proper condition for constant use;
• directly protects the cylinder cavity from the consequences of combustion of contaminated gasoline.

The Hyundai Solaris fuel filter, like many models from this manufacturer, is located in the tank. In its structure, it represents a node consisting of:

• fuel pump;
• gasoline level sensor in the gas tank;
• two filters: one coarse filter element (helps clean fuel from large fractions), the other fine filter element (cleans gasoline from small impurities).

Such an organization of the unit in the Hyundai Solaris allows you to combine several elements of the system into a single fuel module. This is certainly convenient for the design of the car, but not very convenient for repairing this unit. Despite this, the fuel module is dismountable and, if desired, you can replace individual parts, rather than the entire assembly. It is worth understanding that using a dirty fuel filter not only causes considerable discomfort to the car owner, but also significantly reduces the service life of many car parts (fuel lines, injector, engine).

Replacing the Hyundai Solaris fuel filter with your own hands

Replacing the Hyundai Solaris fuel filter should be carried out by specialists at a service station. The service fee is low. But if this is not possible, you can change the spare part yourself, following the instructions provided.

Important! Before starting, you need to release the pressure in the gasoline tank. To do this, simply unscrew the filler cap.

For more detailed information about the procedure, it is recommended to additionally watch the corresponding video instructions.

Stage 1 - gaining access

In order to replace a part on a Hyundai Solaris car, you first need to gain access to it.

1. Using a socket with an extension, we twist the bolt on the mounting cushion at the back, access to which is through the backrest and cushion of the last seat.
2. We remove the pillow by lifting it from the front and removing both front fasteners from the holders.
3. Using a knife, we cut the sealant around the hatch cover on the module, and then move this cover to the side.
4. Turn off the ignition and squeeze the clamps on the wiring harness block.
5. Disconnect the wire connector from the cover on the module.
6. We move the clamp along the hose, after which we use pliers to compress the ends of the clamp, with which the fuel vapor hose is connected to the adsorber, and remove the hose from the cover.
7. Remove the tip from the lid fitting. To do this, press the latches located on the gas supply tube.
8. Using an eight-millimeter socket, we twist the bolts that secure the pressure plate to the module cover and remove this plate.
9. As carefully as possible, trying not to touch the float, remove the fuel level sensor.

Stage 2 - we make a replacement

As a result of these procedures, access is provided to the module in which it is necessary to change the fuel filter. Next, the following procedures are performed.

1. We take out the rubber sealing ring that seals the flange of the hole in the gas tank. We also remove the cover from the fuel module.
2. By pressing the wiring lock of the fuel level sensor in the tank, disconnect the block from the connector on the cover. In this case, we remove the sensor wiring from the clamps.
3. We slide the sensor along the guides in the modular glass and remove it, after prying it off with a slotted screwdriver.
4. Using a screwdriver, pry up and remove the spring retainer.
5. Remove the tube tip and the sealing ring from the fittings at the inlet and outlet of the fuel filter.
6. Remove the tip from the fuel pump tube.
7. We press the clamps on the rod guides and disconnect the fuel module glass from the cover.
8. Disconnect the wiring from the pump.
9. Using a slotted screwdriver, pry up the latches on the cup body, and then remove the fuel filter complete with pump, strainer and pressure regulator.
10. We remove the fuel pump and pipe from the socket inside the filter shell.
11. Using a screwdriver, pry off the washer, remove the filter with the mesh from the pipe and remove the washer itself.
12. Disconnect the tip of the mass cable and remove the tube through which the fuel is drained.
13. Use a slotted screwdriver to pry up the two clamps and remove the clamp.
14. We remove the pressure regulator from the fuel filter, and then disconnect the tube from it that serves to drain the fuel.
15. We remove the sealing ring of the pressure regulator from the socket in the fuel filter shell.
16. We remove the filter, including the sealing rings located on the fittings.

In this way, you can change or repair the fuel filter, carefully examining all non-working parts. Assembling the fuel filter and module and installing them is carried out strictly in the reverse order. Before installing the mesh filter, it is advisable to thoroughly rinse it. The lock washer is straightened or replaced with a new one, with replacement being considered the preferred option.

Upon completion of assembly, start the engine and check the connections for leaks. If leaks are detected, carefully repeat the entire sequence of actions.

Where is it located and how to change it yourself

The location of the fuel module is the same for all Hyundai cars, regardless of the model, engine type and year of manufacture, in the gas tank itself along with the fuel pump, so finding it will not be difficult.

STEP 1. Using a 12mm socket, unscrew the mounting bolt holding the rear sofa in place. To do this, insert the tool between the backrest and the pillow. After this, pull the bottom of the sofa forward and up.

STEP 2: Locate the fuel module hatch and lift it up. To do this, you will need to trim the sealant using a stationery or other knife.

STEP 3. Before removing the fuel module, clean the area around it. This is necessary so that dirt does not end up inside the tank in the future. A regular clean cloth or brush will do for this job.

STEP 4. Carefully disconnect the wires, unclip the hose clamps and unscrew the bolts with a 8mm socket

Next, very carefully remove the fuel module

STEP 5. Replace the coarse mesh and fine filter. If the mesh is in good condition and not torn, then it does not need to be changed, but only cleaned of dirt

Please note that when disassembling the fuel module there is a possibility of losing the o-rings. Therefore, be careful, without them gasoline will not flow into the engine and, as a result, the car will not start

STEP 6. Reassemble everything carefully in reverse order. Don't forget to apply new sealant to the sunroof and check the fuel system for leaks.

Solaris fuel coarse filter

A filter mesh with catalog number 311841R000 . Price - 360 rub. Manufacturer: Hyundai/Kia/Mobis. Buyers have no complaints about the work of the part, and reviews are usually positive. A substitute for the coarse fuel filter is Kross KM7901114 . Manufacturer: Korean company Kross. Price – from 300 rub. The characteristics are practically no different from the original, but the cost is slightly less.

As the experience of car owners shows, the coarse filter does not become very clogged and can easily be cleaned on its own. You can simply wash it with acetone or blow it with air. You can use a simple car pump for this.

Causes of clogging

• unstable start of the power unit at different temperature conditions;
• increased fuel consumption, including under load;
• engine detonation at idle speed;
• acceleration is slower than usual;
• lumbago in the exhaust pipe;
• the car engine chokes as a result of an enriched or lean combustible mixture;
• The “Check Engine” light on the instrument panel is on.

• operating the vehicle for longer than the recommended period before undergoing a scheduled technical inspection;
• refueling with low-quality fuel, low-octane mixture for a long time;
• installation of non-original consumables;
• installation of spare parts from other technical equipment that are similar in appearance to factory ones;
• the machine was left idle for a long time, in the “preservation” mode, as a result of which the circuit became clogged and sediment formed.

Characteristic signs of blockage

• unstable start of the power unit at different temperature conditions;
• increased fuel consumption, including under load;
• engine detonation at idle speed;
• acceleration is slower than usual;
• lumbago in the exhaust pipe;
• the car engine chokes as a result of an enriched or lean combustible mixture;
• The “Check Engine” light on the instrument panel is on.

Access to the fuel module

Before starting work, it is necessary to remove the pressure from the fuel line and dry it, as it will be necessary to disconnect the hoses from the fuel block. There are two ways to do this. The first method is simple

, when the engine is turned on, the fuse that is in the power supply circuit of the pump and level sensor is removed from the fuse box. The pump stops pumping fuel and after a couple of minutes the engine stalls. After this, you need to make a couple of turns with the starter and the pressure in the line will be released.

Another method differs in the method of disconnecting power from the module

. To do this, we begin to disassemble the rear seat. The fastening bolt can be reached through the gap between the seat and the backrest. It is unscrewed by an extension with a 12-point cap. After this, the cushion holders are removed and it is removed from the cabin, freeing up space for work.

Next manipulation

. It is necessary to use a sharp knife to make a cut in the sealant that covers the fuel unit hatch that needs to be opened. Access to the module and plug connector for power supply and signal transmission from the sensor is provided. Now, in order not to look for a fuse for the fuel system, simply pull the plug out of the socket with the engine turned on and repeat the procedure for relieving pressure described above.

The original fine filter for Hyundai Solaris has catalog number 311121R000 . Price – from 950 rub. Manufacturer: Hyundai/Kia/Mobis. The original spare part is equipped with a high-quality filter element. According to the experience of many drivers, the original is able to easily maintain more than the declared service life. There is also an original fuel filter on the market with article number S311121R000 . Cost - 940 rubles. Typically used for post-warranty repairs. There are no differences between the two models of spare parts.

Since the price of original Hyundai Solaris fuel filters is a little overpriced, replacements will be relevant for the owners of this car.

The most popular analogues of a fine fuel filter:

• AMD.FF45 Average price - 700 rub. Manufacturer: Korean company AMD. The quality of the filter paper itself is slightly lower than the original. But this disadvantage is compensated by its density. In general, the design of the part is quite reliable;
• Nipparts N1330330 Price – 570 rub. Manufacturer: NIPPARTS, Netherlands. The part has proven itself well. It has only positive reviews, and on average is 2 times cheaper than the original;
• Finwhale PF731 Average price - 620 rubles. Manufacturer: Finwhale Corporation, Switzerland. Has different reviews. One of the weaknesses of this model is that it does not allow fuel to pass through the filter element.

Where is the fuel filter located on the Hyundai Solaris?

The fuel filter is a small but important part of the car. The fact is that no matter what fuel is poured into the car, it is not always clean. Both gasoline and diesel fuel travel quite a long way in tanks, and then sit in bunkers at gas stations. Mesh pads can only save you from large debris. This is where a fine filter comes to the rescue.

During operation, all gasoline poured into the car passes through this element. Gradually, the filter becomes clogged and the gasoline passes through worse. This leads to a drop in pressure, the load on the fuel pump increases, and the “traction of the car” decreases. Therefore, technical regulations require changing it every 50 - 60 thousand kilometers.

However, this figure is approximate. It is worth considering that if you drive in difficult road conditions, and often have to refuel in an unfamiliar place, then the replacement period is steadily decreasing and is about 30 thousand km. Conversely, if you drive carefully and use proven gasoline, you can leave this unit without replacement if there are no alarming symptoms.

The fuel filter on Solaris is interlocked with the fuel pump. To get to the latter, you will need to remove the rear seat. It is there, under a special cover, that the fuel pump is located, from the block of which the fuel filter is removed.

Replacing the fuel filter on Hyundai Solaris 1.4 - 1.6

Every car enthusiast periodically faces the need to repair and maintain his car. Elimination of most faults and carrying out routine maintenance is most often carried out at service stations. In addition, if the machine is purchased new, it has a warranty period, during which everything necessary is carried out at authorized service centers. However, the need for repairs or maintenance by the owner himself arises with enviable regularity. For example, replacing the fuel filter on a Hyundai Solaris. This part is essentially considered a consumable item. However, its service life is considerable. And some motorists generally drive without making replacements and do not complain about engine performance.

Hyundai Solaris fuel filter

Since 2001, the vast majority of foreign cars have been equipped with an internal coarse fuel filter (hereinafter referred to as PF). External filters are no longer practiced as mandatory standard equipment.

At the same time, such an innovation is both good and bad, since the quality of fuel absorption decreases and the frequency of technical inspection of the machine increases.

TF cleans fuel from all kinds of impurities, debris, and condensation. Contaminated fuel does not burn completely, which contributes to the formation of soot.

Systematic operation of a car with low-quality fuel leads to increased acceleration time, increased gasoline consumption, and unstable operation of the power unit.

Where is the TF located: in the center of the channel under the rear passenger seat. Access for maintenance from inside the car; first remove the diagnostic hatch.

If necessary, replacing the TF on your own is not at all difficult; no special skills are required. If you do not practice independent repairs, then seek help from service center specialists.

When to change the filter

For the first time, you need to pay attention to the fuel purifying element when the car has driven 30,000 kilometers or after two years of operation. Diagnostics will be needed. Its essence is to measure the pressure in the fuel rail using a special device.

If the replacement is not made in time, the next serious problem will be the failure of the fuel pump. This can happen at the most inopportune moment. The required part may not be at hand.

If the pressure in the fuel system does not correspond to the nominal pressure, one of the reasons for this may be a clogged fuel filter. In this case, it is recommended to replace the Hyundai Solaris fuel filter without any disassembly and maintenance.

Instructions for replacing the filter:

Removing the module:

1. ​Remove the back seat. To do this, you need to unscrew the bolt to “12”, located in the middle, between the back and the seat.
2. Remove the plastic cover. The plastic is placed on a sealant; to remove it, you need to heat the edges with a hairdryer.
3. We pull out the wire from the connector.
4. We wash the inner cavity of the hatch to remove dirt so that it does not get into the tank.
5. We remove all the hoses and unscrew the bolts of the pressure washer.
6. We take out the module by hand and pour the remaining gasoline into an empty container.

Parsing the module:

1. ​We take out two metal brackets from the tubes.
2. We bend the plastic clamps of the springs of the metal rods and remove the module cover.
3. Remove the wire from the fuel pump connector.
4. Bend the three tabs and lift the module.
5. Remove the wire from the filter element.
6. Disconnect the fuel pump from the filter.
7. Remove the filter mesh from the pump.

Filter replacement:

1. ​We put a new filter mesh on the pump.
2. We take a new filter element and connect it to the pump.
3. We move all of its detachable parts from the old filter to the new one.
4. We connect the wire to the filter element.

Final stage:

1. ​Assemble and install the module in place in the reverse order.
2. We turn the ignition on and off several times to create pressure in the fuel system.
3. We start the engine, let it run for a while, then turn it off and start it again.

Stable engine operation at idle indicates that everything was done correctly. After completing the steps, you must ensure that the system is sealed

Hyundai Solaris is not a fancy car, but it is important to know how to change the fuel filter correctly. If this task causes difficulties, it is better to contact your dealer or specialized service station.

Self-replacement of the Hyundai Solaris fuel filter (photo and video).

Our instructions are suitable for Hyundai Solaris cars with 1.4-1.6 liter engines, both first and second generation.

When should you change the fuel filter?

The manufacturer has established a regulation - the fuel filter is replaced once every 60,000 km. But, in practice, it is better to change the filter more often, since the quality of fuel at Russian gas stations leaves much to be desired.

A clogged fuel filter manifests itself in the form of a lack of power, failures during acceleration, and a decrease in maximum speed.

If you do not change the fuel filter in a timely manner, problems may occur. One day, a Solaris came to our service with a faulty fuel pump, the reason for the failure was a break in the mesh. Accordingly, dirt got into the pump, and it wore out; the reason for the breakthrough of the mesh was the formation of condensate in the tank and its freezing.

In practice, it is advisable to change the fuel filter every 3 years or 40,000-50,000 km, whichever comes first.

If you live in large cities and drive a lot, the scheduled fuel filter replacement period will suit you quite well.

What is required to replace the fuel filter?

Tools:

• wrench with extension
• 8 socket for unscrewing the fuel module ring.
• 12mm head for unscrewing the seat.
• a stationery or regular knife for cutting sealant.
• pliers for removing clamps.
• flat-head screwdriver for disassembling the fuel module.

Consumables:

• coarse mesh (31184-1R000 - original)
• fine filter (S3111-21R000 - original)
• sealant for gluing the lid (any kind, even Kazan)

The approximate cost of consumables is 1500 rubles.

If you are more accustomed to reading, below are step-by-step instructions with pictures:

Step 1 - remove the rear seat cushion.

To do this, unscrew the mounting bolt with a 12mm head. It is located in the center and by moving it upward we lift the seat cushion, freeing the front brackets.

Step 2 - remove the cover.

This is done using a stationery or regular knife, cut the sealant and lift it.

Step 3 - remove the dirt.

This is necessary so that after dismantling the fuel module, all this dirt does not get into the tank. This can be done using a rag, brush or compressor.

Step 4 - remove the fuel module.

Carefully disconnect all the wires and unclip the fuel hose clamps. After this, unscrew the 8 bolts by 8, remove the retaining ring and carefully remove the fuel module.

Step 5 - service the fuel module.

We replace the coarse filter (the mesh at the inlet to the fuel pump), and replace the fine filter - a plastic container.

ATTENTION! It is extremely important not to lose the O-rings when changing filters. A common mistake is the loss of the sealing rings of the pressure regulator - if you forget to install the sealing rings, the car will not be able to start, since fuel will not flow into the engine

A common mistake is the loss of the pressure regulator sealing rings - if you forget to install the sealing rings, the car will not be able to start, since fuel will not flow into the engine.

Step 6 - assemble everything in the reverse order, glue the lid onto the sealant, install the seat and enjoy the money saved.

To understand the degree of clogging of the fuel filter after 50,000 km of operation, you can look at two photos (filter paper on one side and the other):

Fuel filter replacement process

If you have enough experience, the procedure can be performed in a garage using basic tools. Before you begin, you should find out where the fuel filter is located on the Hyundai Solaris. The location of the module is inside the fuel tank. In order to begin dismantling, you must purchase an original spare part according to the catalog number.

After this, you can begin to remove and disassemble, but first you need to remove the filter from the fuel tank.

Remove the rear sofa by pulling it towards you. First, use a socket wrench to unscrew the 12 nut located between the back and the back of the seat. The plastic protection, located on the left side of the bottom of the car, is secured with a special sealant. To dismantle it, you need to gently heat the contact area that runs along the perimeter with a hair dryer. Treat the surface with a special spray, since a large amount of dust always accumulates between the tank and the outer part of the body. It is necessary to prevent dirt from getting inside the tank. After unscrewing the three bolts, remove the ring holding the fuel filter module. Disconnect the electrical connector. Disconnect the two fuel lines. Prepare a gasoline container in which you can place the fuel module. Drain the remaining fuel and sit comfortably in a bright place. In order to disassemble the fuel filter, the only tool you need is a flat-head screwdriver. Disconnect the fuel lines leading from the cover to the filter element by pulling out the retaining metal clips. Pry up the plastic clips that hold the two metal pins in place. The length of the wires is sufficient to then disconnect the electrical connector from the fuel pump located inside the fuel module. Bend the three plastic tabs and disconnect the assembly that houses the fuel pump and filter. Before changing the fuel filter on Solaris, carefully examine the new part. By comparing it with the old unit, you will intuitively understand which elements and in what sequence need to be removed from the old one and installed on the new one. From the inside, spread the two plastic tabs and pull out the fuel pump. Using a flat-head screwdriver, remove the coarse filter by pulling it off the axis on which it is attached

It is important not to lose the rubber seals. Leave them on the old parts, and during assembly, install each one on a new filter and only then mount the assembly. Start the assembly by installing a new coarse filter, which comes with the new filter. Install the fuel pump into the new filter by snapping it into place with the plastic clips. Transfer all parts from the old filter to the new one.

The developers provide for disassembling and installing a new filter and fuel pump. Therefore, all elements are secured with latches. When dismantling (installing), proceed delicately

Pay special attention to the installation of fuel pipes and rubber seals to prevent loss of pressure in the fuel rail

Install the fuel module into the vehicle tank in the reverse order, being careful not to mix up the fuel supply and return lines.

Don't rush to start the engine. Turn the key in the ignition switch several times, filling the volume of the fuel module. You can tell by the sound whether it is filled with gasoline. After the sound has become monotonous, you can start the car.

Avoid unstable operation of the fuel pump; change it at the first sign of a malfunction or after a mileage of 60 thousand kilometers (after 3 years of car operation). The time when changing the fuel filter may be lost, then you will need to replace a more expensive part - the fuel pump.

How often should it be changed?

Obviously, the replacement period set by the manufacturer does not fit with Russian driving conditions. Low quality fuel, bad roads and other issues negatively affect the service life of spare parts. On Hyundai Solaris, the filter is not a separate part; it is mounted in a universal module consisting of several components. Therefore, it is irrational to remove and check the fuel element every time.

In fact, signs of a clogged filter are visible to the naked eye; identifying them is not difficult:

• fuel consumption increases;
• engine thrust drops sharply;
• in idle mode the engine is unstable, and at higher speeds dips are observed;
• the engine starts poorly in the morning, “when cold”;
• The car jerks when driving and brakes spontaneously.

These symptoms may indicate breakdowns in other parts of the car, but most often the problem is a clogged filter. It must be replaced by first removing it from the module, which is located in the tank of the car. As a rule, the fuel purification element becomes contaminated when the car's mileage is 20-30 thousand kilometers.

When to change

Regardless of mileage, replacing the fuel filter may be necessary in the following cases:

1. The car loses dynamics, the gas pedal “falls” without causing a noticeable increase in traction.
2. After idling, the engine may stall.
3. The higher the speed, the more unstable the engine is. Power dips may occur, especially when the tachometer needle crosses the middle of the scale.
4. When you turn the key in the ignition, the sound of the fuel pump changes. There are problems starting the engine.
5. Fuel consumption inexplicably increases while maintaining normal driving mode.
