In order for the car not to fail on the road and to work properly, you need to monitor its technical condition. It is necessary to identify all faults in a timely manner, carry out repairs and regularly change consumables. The article provides step-by-step instructions for replacing the air filter on a UAZ Patriot, as well as recommendations for replacement regulations.
Design features of the system
While the engine is running, the fuel pump operates and creates constant pressure between the right tank and the fuel rail. In this case, excess fuel is cut off with a special tee installed after the fine filter.
They are discharged under pressure into the right tank, and pass through a special jet pump nozzle. The high speed and thin diameter of the inner pump tube create low pressure in the outer ring.
The result is a vacuum, due to which fuel is pumped from the left tank to the right.
The system is completely autonomous and operates only due to pressure difference. If the left tank runs out of fuel or the right tank is full, the supply stops automatically.
For greater convenience, most components are duplicated. So, each gas tank has its own fuel level sensor, and the body also has 2 filler necks on each side.
The most common problems:
- Fuel filter dirty;
- Depressurization of the system;
- The appearance of sediment in the gas tank;
- Highway contamination;
- The fuel pump is failing.

Replacing the element is necessary if a loss of traction is felt and the car begins to move jerkily. But at the same time, the on-board computer will not generate errors.
To change the element, you first need to disconnect it from the fuel line. Before this, it is necessary to remove the pressure in the system. You need to start the engine and pull out the fuel pump relay.
Now we wait for the engine to stall itself and get to work. The filter is located under the bottom of the car and is secured with two 10mm bolts. The hoses are held in place with special quick releases.
Installing a new one occurs strictly in the reverse order.
Replacing the fuel pump
Before starting work, the right seat is removed. To do this, use a 17 key to unscrew 4 bolts. After this, unscrew the cover on the bottom to gain access to the pump and fuel pipes. It is necessary to remove them and the power supply.
We unscrew the 10 nuts around the circumference of the pump, after which it can be removed from the seat. You need to pull out the part carefully so as not to tear off the float. It is best to tilt the bulb towards the rear of the car.
One of the problems when removing a part can be the corrugated hose mounted on the pipe. It is made of heat shrink material, so heat is required to release it. It is important to remember that you should not use open fire sources for this, since gasoline vapors may remain in the system. It is best to use a hair dryer.
Fuel level sensor
The float on the right tank can be changed both together with the pump and separately from it. The work of replacing it is similar to installing the pump in the previous paragraph. But it is worth remembering that there is also a gasoline level sensor in the left tank. In some cases it may be damaged:
- manufacturing defects;
- terminal oxidation;
- debris deposition.
The same hatch will be located under it.
Replacing the fuel filter UAZ Patriot Euro 4
The fuel filter always carries an important function, and if it is not working properly, then the operation of the power unit becomes simply impossible on any car, including the popular domestic UAZ Patriot.
Since this filter is designed to pass fuel, both gasoline and diesel, through it in order to clean it, therefore, its service life depends on the quality of the fuel consumed.
We invite you to consider what a fine fuel filter is and how to replace the fuel filter on a UAZ Patriot with your own hands.
Fuel filter on Patriot
The fine fuel filter we are considering today, according to the manufacturer, has a working life of 15-20 thousand kilometers. If your car has covered such a mileage, this will still not be an indicator for replacing the filter element.
The need for replacement largely depends on the quality of the fuel consumed and the environment in which the car is operated. Every owner of a UAZ Patriot knows that this is a full-fledged SUV, and on such cars it is customary to change the filter every 10 thousand kilometers.
Again, we draw your attention to the fact that the fuel filter should still be replaced if the driver detects such signs while driving, such as:
- The car won't start at all.
- When increasing speed and while driving, the car jerks.
- The power unit malfunctions at idle.
In such cases, it is necessary to replace the old filter as quickly as possible; the main thing is to know how to remove it and install a new one.
Most likely, everyone knows that the popular UAZ Patriot is equipped with power plants: diesel and gasoline, and everyone can name the differences between them, but not everyone knows what differences exist between gasoline and diesel filters.
The so-called fine fuel filter, which directly cleans diesel engines, has no differences in design from the gasoline version.
However, in addition to the cleaning element itself, such a filter is equipped with special separators designed to separate water from the fuel.
Some machines have a water sensor and a small special faucet that allows you to drain the water.
Important! If your UAZ Patriot is equipped with a diesel power plant, then to prevent condensation from accumulating in the tank, it should be periodically refilled.

We do it yourself by replacing the fuel filter on Patriot
It is necessary to perform some simple steps so that you can then replace the fuel filter on the UAZ Patriot we are considering:
- We leave the car engine turned off for about 20 minutes in order to reduce the pressure in the system.
- We turn off the minus terminal, de-energizing the UAZ with this action.
- The next manipulation will require you to have two keys. We hold the fitting with one of them, and with the second we unscrew the nuts that secure the tips.
- The filter is secured using a special clamp; it needs to be loosened.
- Carefully disconnect the fuel pipes. Do not forget that these same tubes at the joints are equipped with rubber sealing rings that wear out quickly, therefore, they require special attention.
- At this point you can easily remove the filter and remove it from the clamp. Now you know how to remove the filter element step by step.
- Installation of a new element is carried out in the same way as described above. Just before doing this, be sure to make sure that the fluid flow is in the right direction. For this purpose, it is recommended to look at the special arrow.
The environmental standard EURO-3, -4 plays a significant role. UAZ models produced since 2005 are equipped with EURO-4 engines, and until 2005, Patriots with EURO-3 were produced.
Let's sum it up
As a result, I would like to note that a filter element in the power unit of any car, and even more so the UAZ Patriot, is mandatory, otherwise its absence will negatively affect the engine and the electronic fuel injection system. It is recommended not to remove the filter and to monitor it regularly.
Recommendations for selection
The duty of the cabin filter is to qualitatively clean the incoming air, which, along with dust and debris, tends to break into the car’s interior.
There are two types of filters installed on this domestic UAZ model: single-layer and multi-layer. Both do a fairly good job of cleaning the air. However, the latter contain a special layer of activated carbon, which can eliminate unpleasant odors, for example, exhaust fumes from oncoming cars. UAZ Patriot has two types of panels in its design: old and new. This feature affects the selection of the appropriate filter element, namely the size of the part. On cars produced before 2012 and 2013, a conventional single-layer cleaner was installed (art. 316306810114010).
After restyling, the car received a filter with a carbon absorbent (art. 316306810114040). To effectively clean the incoming air flow, many drivers install non-original spare parts, in particular from companies such as TDK, Goodwill, Nevsky Filter, Vendor, Zommer, AMD.
If you change a dirty filter in time, you can avoid the problem of the formation and accumulation of harmful bacteria in the air system of the UAZ Patriot and prevent a deterioration in the well-being of the driver and passengers.
Replacing the UAZ Patriot fuel filter
Continuing the work to put the UAZ Partiot I bought in order, I decided to replace the fuel filter.
I was surprised to discover that there are not so many materials on the topic of how to replace the fuel filter in a UAZ Partiot, and those that exist are not suitable or are only partially suitable.
In fact, there is nothing complicated, but this is for those who know and have already changed the fuel filter. For those who have never changed the fuel filter, I will tell you how to do it.
As is already clear from the name itself, the fuel filter serves to clean the fuel from foreign particles that can get there from the gas tank.
This is not absolute protection, but only the first, so to speak, springboard designed to protect the fuel system of your car. Anything can happen in life - dirt in the fuel at a gas station, rust in the gas tank, etc.
It is in such cases that the fuel filter comes into play.
I purchased a fuel filter UAZ 40904, GAZ dv. EURO-3 (iron case)** UNDER latches (NF2112 B)** / NF-2112 B (NF-012-T EURO Linner 112).
Why are the words “UNDER THE LATCHES” in bold? Because this is extremely important! There are UAZ Patriot models where the fuel filter mounts are fittings rather than latches. Accordingly, a fuel filter for such mounts must be purchased for fittings.
Also, I highly recommend paying attention and taking filters exclusively with a metal body! Plastic ones are a little cheaper, but they can crack in the cold or if you overtighten the clamp.
How do you know what type of fuel filter you need: snap-on or plug-in? To do this you need to find it and look at it. The fuel filter is located on the bottom, directly opposite the right front door.
Necessary tool
In order to change the filter element, you need to prepare all the necessary tools:
- Screwdriver Set;
- New filter;
- Vacuum cleaner or blowing device.
The element through which air is purified is a folded accordion that consists of several layers; for additional cleaning, it can be coated with activated carbon.
Since a replacement filter can be made from various materials, it is worth paying special attention to the selection of the product.
Replacing the fuel filter UAZ Patriot
The dynamic characteristics of a car and the power parameters of the power plant depend not only on the technical condition of the mechanisms, but also on such “inconspicuous” consumables as filters.
Therefore, replacing the UAZ Patriot fuel filter should be carried out not only as part of scheduled maintenance, but in cases where problems are detected with the operating conditions of the engine.
The fuel filter carries out fine cleaning, so depending on the quality of the fuel, it can become clogged quite quickly, which significantly reduces its throughput, and the power unit itself feels its deficiency with a drop in traction.
Reasons for emergency replacement of the UAZ Patriot fuel filter
urgently change the fuel filter on a UAZ Patriot in a number of cases:
- The engine refuses to start with obvious signs of lack of fuel supply, i.e. There is no output even at idle speed.
- When accelerating, the vehicle begins to twitch or there is a complete loss of traction and engine speed.
- The idle speed “floats”, failures in fuel combustion occur, and when you try to reach higher speeds, you feel a failure and “triple”. While driving, this is felt not only as a twitch, but as if, instead of accelerating, an additional load was attached to the car.
It is worth considering that the service life of the fuel filter is nominally 15 - 20 thousand kilometers, but in reality it can only be about 10,000 km, so it is often changed at the same time as replacing the UAZ Patriot air filter. The timing is also similar for replacing the filter in the interior of the UAZ Patriot.
Stages of replacing the UAZ Patriot fuel filter
Important!!! Before you buy a UAZ Patriot fuel filter, you need to choose it correctly, because... for gasoline and diesel engines they are different, and there are also differences in throughput and degree of filtration. It is recommended to select a model by catalog number or article.
To replace a consumable element, you must know where the UAZ Patriot fuel filter is located , because its location differs from the car model range. So, in gasoline models, the filter element can be found under the bottom of the body, but in diesel engines it is usually located in the engine compartment.
The replacement process itself is no different from replacing other consumables. It is necessary to dismantle the old one and install a new one. But to carry out the event without trouble, the car must sit without a working engine for about 20 minutes, because...
Only during this period of time the pressure in the systems decreases to a minimum. Particular attention is paid to the tightness of the fuel line assembly, because seals, tubes and clamps also age and their reliability decreases.
To make it easier to unscrew threaded connections, it is recommended to treat them with any deep-penetrating lubricant.
Important!!! When installing a new UAZ Patriot fuel filter, you must pay attention to the direction of fuel flow. There is an arrow on the filter element. Installation in the opposite direction, although not critical, is not advisable, because interferes with the correct passage of fuel through the filter with the collection of contaminant particles.
Site about off-road vehicles, SUVs, off-road vehicles
On UAZ Patriot and UAZ Hunter vehicles with a ZMZ-409 engine, the air filter assembly has catalog numbers - 3160-1109010-10 or 3160-1109010-11. Catalog numbers of replacement filter elements are 3160-1109080-10, 3160-1109080-11 or 3160-1109080-12.
Modification of the UAZ Patriot and UAZ Hunter air filter housing cover to install a low filter element.
For GAZelle and Sobol cars with ZMZ-405 and ZMZ-406 engines, air filter filter elements are produced that at first glance are similar and suitable for UAZ Patriot and UAZ Hunter. However, when you try to install such a filter element to replace the old one, it turns out that it does not fit normally into the UAZ air filter housing.
This happens because of its height, which, compared to the original filter element on the UAZ Patriot and UAZ Hunter, is two or three centimeters or so less. To avoid confusion, since both of these filter elements can be produced under the same catalog numbers, for example 3105-1109013 or 3110-1109013, and also to somehow distinguish them from each other, sellers usually add the words “low” to their name and "high", respectively.

Well, in order not to bother yourself with searching for the right “high” filter element on the UAZ, and to be able to install the more common “low” filter element into the air filter housing, you need to make a small modification to the fastening on the cover of the air filter housing.
The modification is very simple, does not take much time and does not make any significant changes to the design of the UAZ air filter. It consists in the fact that the L-shaped fastening of the lid is shortened by 3-4 centimeters, and the old pin is replaced with a new longer one.

Good afternoon everyone. I have a Hunter UAZ 315195 2010. I bought it in May. Mileage 35,000 km. Most likely YOU Alexey have not figured out the power system. I do this. I don't open the right tank at all. The fuel gauge switch is turned on to the left tank.
As soon as the fuel level arrow showed that the left tank was empty, I poured 30 liters into the left empty tank. Gasoline, as the right one is consumed, will be pumped automatically into the right tank. The fuel pump is located in the right tank. Once again, I do not fill the right tank with gasoline. It is replenished from the left tank.
The right gas tank cap must be screwed on tightly. The plugs are blind without valves.

I agree with you! I fill only the left tank, the pump pumps it into the right tank, plus the gasoline is filtered on the way to the right tank through an additional filter. I only fill the right one when I need to fill both tanks.
