Its main “heroes” will be those who guard the safety of the “iron horses” - fuel filters. We will tell you in this article what role they play in the life of a car, the difficulty of choosing them and how important it is to replace the fuel filter in a timely manner.

Why are they even needed?

Forced fuel cleaning is a necessity to ensure the performance of any engine running on liquid fuel. Filling the filter cavity, gasoline passes through a layer (there may be several of them) of filter material, leaving on its surface particles of dust, dirt and other solid inclusions that adversely affect engine parts.

If the “food” ration of a car engine is diesel fuel, then an additional separator is required that will help clean the fuel, in addition to mechanical inclusions, from water content.

Its operating principle is based on the fact that water is heavier than diesel fuel, and centrifugal force helps separate them from each other. Due to the specific operation of separators, most of them are heated.

What are they, fuel filters?

There are three main groups:

fuel pre-cleaning filters;
fine fuel filters;
fuel separators.

The first group is not very popular for passenger car engines. In them, the removal of large and small particles of impurities from the fuel is entrusted to one filter.

The second group is the most common. Filters of this type can be either case-mounted with threaded fastening, or in the form of filter elements that do not contain metal.

The difference between coarse and fine filters is mainly in the paper. If preliminary cleaning involves retaining particles measuring 75-100 microns, then final cleaning in the best filters allows you to retain particles up to 3-5 microns in size.

Filter elements can be designed with metal covers (for reliable fastening of the filter material) and can be designed with or without reinforcing mesh. Both are always installed in housings made of heat-resistant material.

This design provides for the presence of repair kits, since re-installation of sealing rubber bands and copper washers is not recommended.

It should be noted that the most popular filter material for fuel filters is paper.

Having been born more than a hundred years ago due to a technological error, it is still firmly in the lead among all filter materials.

To extend the service life of the filter, increase the filtration area and thereby improve the quality of the process itself, the paper is installed in the form of corrugations. The density of the folds in it is such that a “curtain” more than one meter long can fit in an “accordion” with a diameter of 100 mm.

By the way, in the cost of a fuel filter, the cost of filter paper is more than 60%, which means that the manufacturer can reduce its price only by losing quality!

Recently, filter materials based on propylene have been increasingly used and have already earned the approval of motorists. A small sector among filter elements is occupied by those made of fine-pored metal mesh.

The classic shape of fuel filters is the cylinder. Replacement cartridges for separators can be rectangular in shape in a metal or plastic case.

Where is the fuel filter located?

Based on the task assigned to fuel filters, its most logical location in the line is after the gas tank and in front of the engine.

The exact location of the fuel filter can vary greatly among different car brands.

A very popular design solution, for example, among Japanese manufacturers is when gasoline pumps are manufactured in a single housing with a filter. They are installed directly in the gas tank. This design has two significant drawbacks: replacing the fuel filter is only available to service station specialists, and very often the failure of one leads to the replacement of the entire unit.

As for the domestic automobile industry, the designers of AvtoVAZ placed a filter under the hood on their “classics”, which is very accessible for control and convenient for replacement. On later models, the filter was already “hidden” in the rear beam, under the bumper.

If we talk generally about the most common locations of fuel filters, we note the most popular:

rear bumper,
bottom niches,
gas tank,
engine compartment or engine compartment.

Separators and pre-cleaning filters can be installed separately (on the frame) of the vehicle.

Signs of a clogged fuel filter

As we have already noted, fuel quality is one of the main reasons for the failure of car engines. Simply put, one day the fuel filters no longer cope with cleaning what comes from the tank to the engine. To find the root of evil, let's turn to the theory of operation of internal combustion engines (ICE).

Textbooks claim that the highest coefficient of performance (COP) is achieved at a certain ratio of air and fuel in the combustion chamber. Ideally it is 14.7/1.

You can imagine what will happen if this ratio is disrupted due to a clogged filter. Even electronics, designed to control the ideal air-gasoline ratio, will have a very difficult time balancing the situation.

What are the main manifestations of a clogged fuel filter:

Unstable engine operation at idle. The tachometer needle twitches and stubbornly stays at high speeds. New and obviously false notes are added to the melody of the engine. Additional vibration appears. There are frequent cases when the engine begins to “trouble.”
Loss of engine thrust. In simple terms, pressing the accelerator pedal no longer produces the desired result.
The car starts to have trouble starting. There is a clear lack of fuel. All this ultimately leads to the fact that one day your “iron horse” will generally refuse to fulfill the will of the owner, as always, at the most inopportune moment.

Note that the problem of timely replacement of the fuel filter is not new. To help motorists today, some manufacturers offer fuel filters equipped with pollution control features.

The operation of the sensors is based on the difference between theoretical pressure and actual (or inlet/outlet) flow.

In modern cars, the lamp for critical filter clogging is displayed on the instrument panel, which is convenient for receiving a signal that it is time to change the “guard of cleanliness”.

Typical faults

Normal engine operation is impossible without a constant supply of fuel. Signs of problems: in the fuel pump:

engine tripping;
power reduction;
the occurrence of extraneous noise;
the operation of the fuel pump cannot be heard;
the car refuses to start;
The engine starts to stall frequently.

What causes a fuel pump to malfunction:

use of low-quality fuel with a high content of harmful impurities;
contamination of the internal part of the unit, rust;
overheating or voltage surge in the on-board electrical network, leading to engine failure;
wear of the seals, as a result of which the tightness of the unit is lost and a leak appears in the housing, while air ends up inside the fuel pump;
mechanical damage caused by unprofessional repairs;
contamination of the filter and fuel conducting channels.

Repair features

The problem of fuel pump contamination can easily be eliminated by simple cleaning. However, this unit is fragile and highly vulnerable, so carrying out such work requires responsibility and professionalism from the master. It is recommended to start repairing the fuel pump as quickly as possible if the moving vehicle often twitches, the speed drops, or the tachometer needle sways.

The success of instrumental diagnostics is determined by the type of drive and vehicle design. It is better to identify the cause of the breakdown through a comprehensive check using computer equipment. New cars have many sensors, each of which can fail.

How to replace the fuel filter?

It is advisable to replace the fuel filter in conditions that ensure comfort and safety of the process. The optimal conditions for this procedure are a car service with a lift. A garage with a pit or a special overpass are also good options.

If all this is missing, and replacing the filter requires efficiency, then a standard jack can serve as a solution to the problem. How to use it is a topic far from our article, but it is worth recalling safety precautions.

Important!

Firstly, work should be done on a horizontal area and with the engine turned off. In addition, the engine must be allowed to cool.

Secondly, motor fuel is a flammable liquid, so the presence of open flames, sources of high temperature and smoking during operation must be excluded!

Thirdly, before changing the fuel filter, you should consider possible fuel leakage, which will inevitably harm the environment. Please take care to minimize possible damage to nature.

If the procedure for removing the old filter and installing a new filter requires the use of special keys and devices, then use them and do not resort to the help of improvised means. When installing the filter, it is advisable to pre-lubricate the O-rings.

Motor fuel may well be suitable as a lubricant. The threaded connections are tightened tightly, but without overtightening, which borders on jamming and even stripping the threads.

If the filter design provides for a settling tank, then you should not forget to remove sediment from it. Many cars (especially those with a long service life) use fuel filters, the replacement of which requires no special tools.

Since you are so “lucky”, then you should not skimp on the metal clamps that secure the fuel pipes to the filter fittings.

The cost of the clamps is low, but a leak in the fuel line can lead to serious problems.

Frequency of replacing the fuel filter

Don't believe those who say fuel filters should last forever. Laboratory tests on premium quality gasoline under ideal conditions and in gentle modes confirm that fuel purification agents have a very, very definite resource.

Now we make allowances for the quality of domestic fuel, admit that our driving style is far from ideal, apologize to the engine for cases of extreme loads and listen to the opinion of professionals about how often the fuel purity guards need to be changed.

The optimal interval for replacing the fuel filter is considered to be 20 - 25 thousand km.

In order not to get confused and not to miss the moment when to change the fuel filter, you can set a rule for yourself: for every even oil change, change the gasoline purifiers.

The opinions of motorists on the frequency of replacing filters may differ both up and down, but we admit that this is the case when it is not worth risking the health of your car’s engine.
