Fuel entering car engine, must not contain any foreign particles. Therefore, in the design fuel system A special filter is included, the basis of which is filter paper. This allows you to detain accidentally caught in fuel tank dust or water before they enter the engine combustion chamber.
Where is the fuel filter located in the VAZ-2114
The fuel filter on the VAZ-2114 is located on the bottom under the trunk and is included in the fuel line. If you look in the direction of travel of the car, it is fixed slightly to the right of the muffler. To carry out work to replace it, you need a garage with an inspection hole.
On carburetor versions of the car (limited edition, first releases) this part is located next to the fuel pump.

Symptoms of a problem
- The engine stops after idling for a short time.
- Fuel consumption is increasing.
- Difficulties in engine operation.
- Jerking or sudden stopping of the engine while moving.
Tools for work
To dismantle the filter element, you need the following tools:
- Container for draining gasoline.
- O-rings.
- Open-end wrenches ranging in size from 10 to 19 mm.
How to change it yourself
Before starting work, the vehicle's on-board electrical system must be de-energized. You also need to relieve the fuel pressure in the system, for which the fuel pump is disconnected from the power supply and the engine is allowed to run until it stops on its own.

Differences on cars with carburetor and injection engines
The VAZ-2114 car is equipped with injection power units volume 1.5 and 1.6 liters. There is a difference between these models in the way the fuel lines are attached to the filter element. These are the fittings mentioned above on a car with a 1.5-liter engine and spring clamps on a car with a 1.6-liter engine.
Since the first batches of cars were produced with a “21083” carburetor engine, it’s worth telling how to change the filter on such a car. The progress of work is not fundamentally different, but the type and appearance filters will be strikingly different from their injection counterparts. So, the algorithm:
- Loosening clamps on gas hoses.
- Removing the worn fuel filter.
- Installing a new filter. This must be done so that the arrow on the body points to the fuel pump.
After installing the filter, you need to make sure that there are no fuel leaks through the fuel line fittings. If there is leakage, tighten the nuts that secure the pipes. It is important to take into account that the device must be oriented along the arrow marked on it, which shows the direction of movement of the fuel. In the case of the VAZ-2114, the arrow should point to the right side of the car.
Replacing the fuel filter on other car models.
On a VAZ 2112, replacing the fuel filter is always a responsible procedure. First of all, this is explained by the fact that the car owner does not know which filter is best to install.
The quick replacement of the fuel filter in the 2112 VAZ is, of course, also due to the quality of today’s gasoline. But still, if the filter is the best, its service life is much longer.
General overview
This same filter must be changed on time, because if this is not done, the negative consequences will directly affect the reliability of the entire car. Let’s first find out what the features are and which one is better to choose.
Today there are many types of fuel filters: for carburetor and injection engines:
- If the filter is intended for carburetor system, then its location is between the tank and the carburetor itself. Thus, the successful location of this element prevents the carburetor jets from clogging with various debris that is present in modern fuel in large quantities.
- In this case, as on the VAZ 2112, the filter will be located under the car. As for injection systems, which are much more sensitive to contamination, compared to carburetor systems, the filter here needs to be changed faster.
Note. It is recommended to change this very element every 30 thousand km of the car. But this applies only to those cases when it is used high quality gasoline. Due to the fact that today you cannot be 100 percent sure of the quality of Russian fuel, the filter must be changed every 20, or even 10 thousand kilometers.
It's no secret that some motorists, mostly newbies, have no idea that this filter needs to be replaced. They continue to drive and with one fuel system protection they reach up to 100 thousand km, or even more.
And in the end, they constantly complain that the car doesn’t work, it’s not the same as before, the VAZ 2112 is not a car, and so on. But it was only necessary to replace the filter when it was necessary and such problems would not have arisen.
Here is a partial list of problems that arise when untimely replacement filter:
- a loss ;
- bad plant, both in winter and in summer;
- extra load on the fuel pump, which starts working at double speed, etc.
Knowing how to choose a good filter is like an art. There are many parameters to consider here, but one thing is certain: the quality of the paper is of no small importance.
Note. Experts advise disassembling the old filter, sawing it and examining the contents. This way it will be possible to create the correct idea of what and how is inside.
If you don’t want to disassemble the filter, then you can listen to other motorists who prefer one filter or another. It will be useful to visit various forums where the pros and cons of this or that manufacturer are discussed.
Evaluation of modern filters for injection systems
If earlier, when under the hood domestic cars There were carburetors, there were no such requirements for the fuel filter, but today, with the advent of injectors (see), everything has changed. New system nutrition, which involves injection, is a delicate and fastidious creature.
Give her only the best, and rough gasoline will certainly not make her feel good. And whatever fuel there is, injectors cannot tolerate dirty air, and it must be clean.
Review
So:
- According to many motorists, the best filters for the VAZ 2112 will be filters from Bosh. Why are they better than the rest?
According to experts, these filters will perfectly protect the entire fuel system not only from solid or water particles, but also from impurities that live in modern gasoline.
- In second place are Champion filters. They are produced not only for petrol versions cars, but also for diesel ones. An ultra-effective level of filtration of impurities and contaminants, elimination of foreign matter and other advantages distinguish this Belgian filter from the mass of others.
- The ideal purity of the fuel entering your car's system is guaranteed by Mann filter manufacturers. They reliably protect the injection mechanism of the injector, removing various impurities and contaminants from the fuel. Dust, rust and water will not get past this guard.
- The filter for which the majority of Russians voted. This is Nipparts, which produces mostly spare parts for Japanese and Korean cars.
Today, fuel filters from this well-known manufacturer occupy not the last place in the list of the best in Europe.
Replacement
The information provided above will help you choose a good filter that is reliable and efficient. You no longer have to worry about contamination of your car’s fuel system, although you still need to change this filter after a certain time. Now let's find out how to replace the filter.
detailed instructions
So:
- So, first of all, you need to de-energize the battery.
- Then, holding the key fuel filter, unscrew the fitting with another key.
Note. At this point, you will need to place some kind of container under the fitting so that the gasoline does not simply spill out onto the ground.
- The second fitting is subjected to similar dismantling.
- Now you need to loosen the clamp holding the filter. We use the key for 10.
- Remove the filter.
- We install a new one.
Note. When installing a new filter, you need to follow the arrow marked on the housing. This same arrow should be directed in the direction of fuel movement, that is, look at the left side of the VAZ 2112.
After installing a new filter, it is recommended to check the tightness of all connections, doing this manipulation with the engine running.
When installing the filter yourself according to the instructions, it is also recommended to study photo and video materials. The price for such services in services today is very high. For this reason, learning how to carry out this operation yourself will be extremely important.
Fuel filter is the same consumables, like gasoline, the more fuel passes through it, the more clogged it becomes, and the sooner it needs to be replaced.
The arrow indicates the direction of fuel flow
How often should you change the fuel filter? The range is very different: on some cars it needs to be changed every 10-30,000 kilometers, on others it is designed for the entire period of operation of the car.
If you don't change it in time..
All fuel passes through the filter, bringing with it any debris - dirt from outside, corrosion products, etc. Over time, the filter element becomes clogged and stops passing the required amount of fuel through it. Since the throughput drops, less fuel passes through it, and the pump still operates at the same performance, where will the excess gasoline go? That's right, it will increase the pressure in front of the filter and thereby increase the load on the pump, which will lead to its rapid wear.
A clogged filter will affect the injector by a drop in pressure in the rail, which will result in poor acceleration when driving. sharp acceleration and the gas pedal will not be as responsive as the first noticeable sign of a clogged fuel filter. And all because the mixture turns out to be lean, there will be insufficient fuel. Most likely, the oxygen sensor will show this and the “ check engine“, you’ll have to go find out what kind of error this is, the handy mechanics will dismantle half the car because they don’t know what computer diagnostics done with new spark plugs, a new fuel filter and normal rail pressure and a charged battery. Therefore, change the fuel filter on time.
