Replacing the fuel pump on a Ford Focus 1,2,3 with your own hands: how to change the motor of the fuel pump, filter, relay

How to remove the fuel pump on a Ford Focus 2 with your own hands

This is how I drank it.

Before changing the fuel pump, let's decide on the methodology, since there are two ways to remove the module - officially , the fuel module can only be changed with the fuel tank removed. There is an alternative way : you can cut an inspection hatch in the bottom of the car under the rear seat cushion and thus get to the fuel module. This method is quite popular, but has some disadvantages:

we violate the integrity of the bottom;
Interior sound insulation suffers;
additional pockets of corrosion may appear;
There is direct contact between the fuel tank and the passenger compartment, and safety suffers, especially during work related to dismantling the fuel module.

On the plus side, we can repair or replace any element of the fuel module at any time; all you need to do is remove the rear seat cushion.

Correct method (official)

Let's start with the official method of replacing the fuel pump by removing the fuel tank. In fact, there is not much work, the main thing is to have an inspection hole, a lift or an overpass.

Relieve pressure in the fuel system. To do this, with the ignition off, remove the fuel pump fuse F111, start the engine and, at idle speed, use up the fuel remaining in the pipes.
Remove the terminal from the battery.
Having placed the car on an overpass or lift, we go under the car.
Remove the fuel filter.

Once the pressure has been released, you can remove the fuel filter.
Unscrew the 2 nuts securing the heat-protective casing of the tank with a 10mm socket.
We move the casing to the side.
We remove the tubes from the adsorber, it is located behind the fuel tank. To do this, press the lock button with a screwdriver and simply pull off the hose.
At the front of the tank, remove the fuel hose from the tube by prying the white plastic clip with a flat-head screwdriver. The fuel is under pressure, so remove the tube carefully as it may spill or splash.
Disconnect the filler neck hose. It is fixed to the tank with a clamp. Loosen the clamp by unscrewing the tightening screw and remove the hose. Attention! If the gasoline level is higher than the nozzle, it may overflow from the tank.
We disconnect the air outlet thin tube near the filler pipe, freeing it from the clamp.
Using a 13mm socket, unscrew the bolts securing the gas tank to the body, but not completely.
We pass our hand between the bottom and the front of the tank, disconnect the contact connector on the hatch cover in the upper part. To do this, press the connector latch with a screwdriver and disconnect the contact blocks.
We remove the tank by moving it forward and lowering it down.
We remove the tank. Somebody, but without barbarism and sawing.
We thoroughly clean the surface of the tank from dust and dirt, especially in the area of the fuel module.
Unscrew the plastic threaded washer. To do this, take a wooden spacer, rest it against the edge of the washer and, with light blows, unscrew the washer securing the module.
Carefully remove the fuel module assembly, inspect the condition of the tank from the inside, look for the presence of suspended matter in the fuel, and, if necessary, rinse the tank.
New fuel pump installed.
We install the new fuel pump according to the marks, aligning the mark on the tank and the arrow on the pump.

Assembling the gas tank and installing it is carried out in the reverse order.

Replacing the fuel pump from the passenger compartment

Be prepared for the fact that when replacing the fuel pump on a Ford Focus, without removing the gas tank, you will have to cut metal.

This method involves replacing the pump without removing the tank from the car, but to do this it is necessary to cut a hatch in the bottom under the rear passenger seat using metal scissors. Work should be carried out either outdoors or in a well-ventilated area to avoid the accumulation of gasoline fumes. We cut out the hatch, focusing on the wiring harness passed into the bottom under the floor covering.

For aesthetics, you can also cut out a circle with a diameter of at least 250 mm.

The diameter of the hatch must be at least 250 mm; when cutting out the circle, we leave a small sector for bending the sheet.

Having cut out the hatch, we gain access to the fuel pump, but working with the pipes and the threaded locking washer will not be as convenient as with the tank removed. All operations for removing and installing the pump are carried out according to the same algorithm as described above, and the hatch can be closed with a new sheet plate with a diameter of about 300 mm, placing it on short self-tapping screws.

The length of the screws should be such as not to damage the plastic tank.

Removing the gas tank

The process of replacing the fuel pump of a Ford Focus car begins with removing the protective covers that prevent access to the unit. It is necessary to remove the absorber tube by using a screwdriver and pulling it off the pipe. The fuel supply hose located nearby is identically eliminated. It is necessary to carefully pull out the pipeline so as not to be splashed with residual gasoline in the system under high pressure.

Now you need to remove the tube that goes to the neck of the tank and is securely secured with a clamp. After unscrewing the fastening, you should remove the hose, prudently placing a container that prevents the spilling of gasoline, the level of which exceeds the nozzle. Then you need to remove the second absorber hose.

Attention! The tube mounts are often contaminated with sand, so it is advisable to tap the hose and knock out the mount.

Consistently eliminating obstacles, we got to the gas tank of a Ford Focus, which can be removed using an electric twister and a screwdriver. It is necessary to remove the fastening elements, and then the tank, being extremely careful so as not to break the plastic and rather fragile container.

Useful information and nuances of installing filters

It’s interesting, but original filters for Ford Focus are practically never found on sale. Thus, the manufacturer forces you to change the entire pump assembly. The Ford Focus car uses two types of filters: FGO (for coarse cleaning), which is a mesh, and FTO in the form of a flask.

The purpose of the filters does not need to be described in detail. Let's just say that they efficiently clean fuel in two stages. This practice has long been found in the automotive industry: one filter removes all large particles of debris (mesh), the other qualitatively cleans the fuel before it is directly supplied to the engine.

The coarse mesh on the Ford Focus is located inside the pump

Fuel filters on a Ford Focus can have different designs and be located in different places, depending on the modification and system of the car. For example, on injection internal combustion engines, the FTO remote filter is located near the tank, and the FGO mesh is located inside the fuel pump.

On a Ford Focus, the FGO mesh is considered a disposable, non-removable element, and according to factory instructions, it can only be replaced when assembled with a pump. The replacement schedule for FTO (external) is every 60,000 km, for FGO (submersible) – every 120,000 km.

The location of the FTO on diesel Ford Focus is interesting. It is located at the back of the engine; the filter element itself is made of paper. The replacement period for such a filter is correspondingly reduced to 25,000 km.

Replacing the remote filter is quite easy. You need to crawl under the car, which you have previously placed on a lift or pit. Before doing this, you should put on protective gloves and open the sash or window in the garage to allow benzene vapors to escape. To ensure fire safety, it is recommended to turn off all heating devices.

Next you need to act in the following sequence:

Pour some fuel into the tank, start the engine and wait until it turns off (the system runs out of fuel - the pressure is released).
The filter is attached to the body with a bolt, and you need to unscrew it.
Disconnect the fuel hoses going to the filter (prepare an empty container in advance into which the fuel remaining in the pipes will be poured).
The filter can then be removed by disconnecting it from the clamp.
Tighten the new FTO into the clamp.

It is extremely important not to forget to mark the tubes, hoses and fittings that we remove.

The Ford Focus remote filter is located separately from the pump

When installing a new filter, you should pay attention to the arrow marked on the housing. It indicates which side of the filter element should face the engine (that is, the filter should be placed so that it is directed with the arrow towards the car engine).

The arrow on the filter should point towards the engine during installation.

Replacement of the mesh is carried out together with replacement of the pump. However, there are motorists who know how to clean the mesh without changing it. There is another option: install a mesh from another car model at the inlet of the original fuel pump, thereby creating additional filtration. This is something like an upgrade designed to improve the stability of the engine for some time. In fact, only a full replacement of the element will make it possible to improve the dynamic and technical performance of the engine if the submersible filter no longer copes with its duties.

Almost all Ford Focus have a hole cut on top of the fuel tank, which is provided for removing the pump and filter without dismantling the entire tank.

The replacement algorithm looks like this:

The rear sofa reclines.
The wires going to the pump determine its location.
Wires to the fuel pump will help determine its location
If the hatch is not provided by the manufacturer, then you should use metal scissors to cut and bend the iron just enough so that it is enough to remove the pump.
A hatch cut out with scissors will provide easy access to the pump.
The pump is held on by a nut that must be unscrewed.

After the pump is dismantled, you need to remove the bottom plastic cover protecting the mesh.

The submersible filter is located inside the pump, it is hidden by the bottom plastic cover

All that remains is to remove the submersible filter and replace it. If the pump is being replaced, then you need to install a new unit in place of the old one. After assembly, be sure to pump some fuel into the system with the starter, but do not start the engine. Then you should check the connection for leaks. The car must also be tested in motion. If there are no leaks anywhere, all hoses and tubes are properly secured, then you need to drive the car at speed along the highway, then downhill. This is how the fuel supply is checked in different driving modes.

Some owners take old fuel pumps to car repair shops, where the units are repaired and put up for sale. If you don’t want to throw away the part, then you can do just that and make some money.

Installing a new unit and testing the system

We replace the Ford fuel pump, focusing on the mark on the gas tank and helping to position the part correctly.

Attention! It is possible to make it easier to replace the fuel pump by treating the top cap of the tank with hermetic lubricant.

Using a block as a handy element, tightening the fasteners until they stop. Ford parts are assembled in the reverse order:

the gas tank is raised;
the tubes are connected to hoses inserted into standard connectors;
The tank is screwed on.

Now you should test the operation of the Ford Focus system by starting the engine. Immediately after turning on the ignition, a sound should be heard indicating that the fuel pump is pumping fuel. If the Ford Focus engine starts, we can talk about a correctly carried out replacement.

Attention! It is advisable to check the hoses for leaks. If fuel leaks, you need to turn off the engine and tighten the clamps with fasteners.

Replacing the fuel pump for the Ford Focus 1 model is required if the filtration system is clogged. The mesh element located between the tank and the fuel pump suffers. Such an incident is associated with pouring gasoline of poor quality, containing additives that tend to settle on the filter. The mesh gradually becomes clogged due to pollen, dust and sand entering the system.

When to change the fuel pump on a Ford Focus 2 according to regulations

Considering the quality of our fuel and the amount of solid fractions that can enter the tank during operation, you can forget about the standard service life of the fuel module. Repair or replacement of the unit is carried out when the pump fails or ceases to pump the nominal pressure into the system. Signs of a fuel pump failure can be different:

After turning the ignition key, the pump does not turn on, and therefore the engine does not start. The operation of the fuel pump electric motor can be clearly heard when the engine is not running. If, after turning the key, the pump relay activated (it made a characteristic click), but the pump did not start, the problem is either in the contacts on the pump connectors, or in the electric motor, or the pump overheated (clogged) and jammed.
Insufficient pressure in the fuel system. In this case, the engine will start, but failures will appear under load, at high speeds, and during acceleration. In this case, idling may be quite normal.
An early sign of a worn pump is a loud noise in the area of the gas tank when the engine is running. The noise will indicate that the pump will soon need replacement.

Removing the fuel module will also be necessary if the coarse filter is clogged, or when replacing or repairing the fuel level sensor.

Causes of fuel pump problems

The true reasons for the failure of the fuel pump in a Ford Focus 1 will become clear only after a high-quality Ford diagnosis. Any visual methods for assessing a malfunction can only help to suspect a fuel pump malfunction. But until the Ford Focus 1 has been diagnosed, there is no need to rush to replace the fuel pump.

Clogged filter in the fuel pump

One of the reasons for the failure of the fuel pump in a Ford Focus 1 is a clogged filter mesh installed at the gasoline inlet from the gas tank to the fuel pump. This problem arises for two reasons: firstly, due to low-quality fuel, which contains additives that also settle on the fuel pump filter. Another reason is the entry of various particles from the external environment into the tank: plant particles, pollen, even small grains of sand can gradually clog the filter mesh.

Fuel pump overheating

Some drivers have heard that driving a car with an empty gas tank has a bad effect on the performance of the gas pump. However, not everyone knows about the reasons that cause the deterioration of its performance, and therefore they are in no hurry to pour gasoline into an empty tank.

The bottom line is that the Ford Focus 1 has a submersible fuel pump , and the gasoline flowing from the tank into the fuel pump cools it. When the gasoline in the can runs out, the degree of cooling of the gasoline pump also decreases. At the same time, it begins to overheat and fails. To avoid this, do not let the gasoline level drop below 10 liters. In other words, don't let the red light come on.

What fuel pumps are installed on the Ford Focus: models, design, location

In the fuel supply system of Ford Focus cars, the fuel pump plays the role of transporting fuel from the tank to the engine. It is advisable to install original spare parts on these cars https://www.habtradedv.ru/catalog/firm-cummins/. But they are expensive. Therefore, some are content with alternative options. For example, Italian ERA gasoline pumps are quite popular.

A few interesting points about Erov’s models:

ERA is not a manufacturer, but a supplier of spare parts. It does not produce anything itself, but is only a packager of certain components. Thus, a fuel pump for an American car packaged by this company can also be considered an original part;
Often on the market you can find fuel pumps packaged in the same boxes with the Mesmer inscription. The price of the models is almost half that of ERA products. What's the catch? It turns out that this is a “left-handed” pump, most likely made in China;
It is recommended to carefully check the Messmer fuel pump in the package
To identify a fake, it is recommended to look first at the label of the packaging box. The “Chinese” sticker is of lower quality, printed on a black and white printer. Secondly, look for the presence of a protective film on top of the pump, on which the ERA brand name should be applied. As a rule, it is not present on fakes;
The ERA inscription inside the packaging indicates the originality of the product
the presence of the Visteon label on the top of the pump can also be considered a signature feature of a real Ford product;
Visteon label on the fuel pump as a sign of quality and originality

Similar fuel pumps that fit the Ford Focus without any problems are from the Volvo S40, Mazda 3. They cost a little more than the Italian ones, but are cheaper than the original ones.

In terms of design, the original fuel pump of Ford Focus cars is a model of an electric submersible rotary pump. The pump is equipped with coarse and fine filters and a pressure regulator. The submersible version of the pump model is considered the best today, as it reduces the risk of vapor locks. Fuel here is supplied under pressure, and not as a result of vacuum.

Original fuel pumps for Ford Focus are made in the USA. The price for parts is about 3–5 thousand rubles. (in times of shortage the cost jumped to 20 thousand rubles). Analogs, as mentioned, are almost half the price.

Ford Focus fuel pumps can be identified by catalog numbers:

1234552;
1254193;
1305354;
1309160;
1312617;
1529595.

There is no particular difference between fuel pumps for Ford Focus cars of different generations. However, it is recommended to indicate the year of manufacture and engine modification when purchasing.

All pumps for American cars are designed for flow rates from 3 to 4.15 bar. Capacity 90 l./h. can be considered sufficient. However, on the latest generation cars with a more powerful engine, it is advisable to select models with a capacity of 115 l/h. If the pump capacity is low and the engine is powerful, this will lead to unnecessary loads on the internal combustion engine and the fuel pump. It is also important to know that the Ford Focus comes with pump models 11.5 cm long and 38 mm in diameter.

The fuel pump is located on the top surface of the tank, next to the hatch. You need to remove the rear seat to get to it (on sedans) or climb from the trunk side (in hatchbacks). However, when developing the car, the engineers did not take into account that the pumps, although original (of high quality), are not at all eternal. If they had provided a hatch under the seat, dismantling the pump would have been much easier. Here the pump is placed directly into the tank. To remove it, you have to cut the tank.

Removing the fuel pump from Ford Focus cars is fraught with significant difficulties

How to remove

Removing the Ford Focus 1 fuel pump becomes the first step in the procedure for replacing the fuel pump. In order to remove the fuel pump, on Focus 1 you will have to dismantle the entire gas tank in which the fuel pump is installed. This should be done with the gasoline drained and the pressure in the line released.

The process of removing the gas tank:

Remove the gas tank cap
Disconnect battery terminals
Unscrew 2 nuts from the release fastener
Remove the unscrewed piece of the outlet, fix the remaining part
Remove heat shield
Remove the hoses that are plugged into the tank
Loosen the clamps and remove the hoses from the black box located behind the tank
Here you can put marks on the hoses themselves and at the place of their installation so that later it will be easier to assemble everything
Remove the black box - to do this, press the plastic latch-fastening
Press the gas filter lock and remove the tube, then remove the tube located next to the red element
Carefully remove the bolts securing the fuel tank slide. In this case, it is better to hold the tank itself - an assistant can do this, or the tank can be supported with a handy tool
Remove the skids and remove the hoses from the clamps
Carefully, ensuring the safety of the hoses and wires, lower the tank
Remove the connectors from the gasoline level sensor and from the pump.
Remove the gas tank from under the Ford Focus 1
Remove the tube from the fuel pump and remove the gas filter from the tank.

It is better to remove the Ford Focus 1 fuel pump from a pit or on a lift.

Important points

When unscrewing the fuel lines from the pump, you must be extremely careful and under no circumstances point the tubes at your face or towards the front seats, since the gasoline in them is under pressure. It is best to unscrew the tubes after wrapping the couplings with a rag.
Since after all the above operations a round hole appears in the floor of the cabin, it must be repaired. For this, a square metal plate (dimensions: 30 by 30 cm) is suitable, in the corners of which holes are drilled. The floor in the cabin is thin, so the plate is easily attached to 4 self-tapping screws. This will reliably protect the pump from damage.
To make it easier to cut through the floor panel with scissors, you can pre-drill a series of holes where the cut will be made. This can be done with a regular electric drill. However, the drill should not be too long, since in this case there is a risk of hitting the gas tank (and it is very easy to damage it, since it is plastic on the Ford Focus 2).

Of course, the method of replacing the pump given in this article can hardly be called beautiful. But it has three undoubted advantages. Firstly, it’s fast, and secondly, it’s simple, so even a novice car enthusiast can complete this task. And finally, it’s cheap, because you won’t have to pay auto mechanics at the service center to completely remove the gas tank and a lot of related operations.
