The fuel filter is an important component of the internal combustion engine, on the correct functioning of which the operation of the car as a whole directly depends. Its main purpose will be to finely cleanse the fuel coming from the gas tank and prevent the penetration of dirt and harmful components into the combustion chamber.
In order for the engine to serve the period specified by the developer and not cause problems to the owner of the car, it is required to properly monitor the condition of the filter, change it in time. To choose a quality device, this rating was compiled, which included the best fuel filters in 2020.

Fuel filter selection parameters
The question often arises as to which fuel filter is better. Given the critical filter element, careful consideration must be given to its selection. Compliance can be assessed due to the following criteria:
- Developer. It is necessary to choose products directly from high-quality manufacturers. Budget segment products are bought only in a situation when there is an urgent need and there are no alternative solutions.
- Replacement frequency. Regardless of the instructions of the developers, the interval for replacing the filter element must be shortened to 2-3 engine oil changes.
- Density and quality of the filter. When choosing a filter insert, you can set its quality yourself. The material used to make the filter is dense and rigid, and at the same time allows gasoline or diesel fuel to pass through, preventing excessive loads on the pump.
- Filtration fineness. An indicator that determines the size of the fraction, guaranteed to be retained by the insert of the filter element. For cars powered by diesel fuel, this parameter will be 5 microns, for gasoline - about 10 microns.
- The guaranteed level of cleansing. The measurement is carried out as a percentage, reflects the number of elements holding the filter element. In the best models, this figure is 98-99%.
To know which fuel filter is best to install, you need to familiarize yourself with the rating.
For injectors

- there is an anti-drain valve;
- compactness.
Minuses:
- overpriced;
- due to the small size of the filter, it requires frequent replacement.
For carburetors
It is a special tool that has no outer shell. It integrates directly into the fuel line of the engine, the installation site will be a special section under the hood. Taking into account the design of the car, the filter has various parameters, in the form of a cylinder or a cone.
"Nevsky filter" NF-2000
Filter elements from the manufacturer "Nevsky Filter" are produced in St. Petersburg or Saratov. The holding that owns the company is also the owner of CJSC Filtration Materials, a domestic developer of filter paper. The manufacturer mainly focuses on domestically assembled cars.
The filter element of the product in question is intended for old cars with a carburetor. Small transparent body with plastic sleeves and small filter. Such a device is supplied unpacked, in an ordinary polyethylene bag, however, data on the manufacturer and model of the product are printed on the case.
Pros:
- compatibility with many Russian cars;
- for a long period, replacement is not needed - some of the products will withstand up to 40 thousand km of run;
- adequate cost;
Minuses:
- small filter area.
FILTRON PS 842
The filters under consideration from the FILTRON manufacturer occupy leading positions in the equipment of any car. The developer is considered a leader in the production of filter devices.
Affordable, but at the same time quite effective gasoline filter for engines with a carburetor. The release is carried out by a manufacturer from Poland.

For diesel engines
The main purpose of such products is to prevent the ingress of abrasive impurities and resins, formed as a result of chemical reactions, into the fuel line and combustion chambers.Due to the high concentration of moisture in diesel fuel, appropriate filters condense water and remove it in significant quantities from the fuel supply equipment.
MAHLE KX 204 D
The filter cartridge from one of the most expensive developers in the automotive market actually justifies its own cost. Here they use high-quality paper, and the folding technology excludes contact and crushing of the ribs and during mechanical action.

How to determine the quality of a fuel filter?
Even well-known developers are capable of producing defective products that somehow were not noticed in acceptance. Directly because of this, when choosing a filter, it is required to focus on such nuances:
- Paper quality and weight. It will affect the filtering performance - the more uniform the thickness of the paper, the better the filtration and less chance of dirt passing past the filter element.
- Winding density. The higher the quality of the filter, the greater the density of the winding and the better the performance of the device.
- Uniformity of filling with dirt. When, during the dismantling of the spent filtering element, non-uniformity and unevenness of filling are noticeable, it is necessary to abandon the purchase of such a device in the future or reduce the terms of use to 8-10,000 km.
Features of choosing a fuel filter for a diesel engine
Due to the nuances of the design, a diesel car declares increased requirements for fuel quality. According to statistics, 80% of the total number of breakdowns of cars with diesel fuel are directly related to the fuel system. In this regard, such a filter for must have the following characteristics:
- material - dense cellulose or synthesis of synthetics and cellulose;
- the form factor matches the design of the car;
- purification level - 99%;
- dimensions of the filtered fraction - no more than 5 microns;
- the presence of a built-in moisture separator.
A useful option is fuel filter heating - a system that allows you to increase the temperature of the fuel in the filter to the required level. Thanks to it, it will become easier to start the engine at low temperatures.
The question often arises as to which fuel filter is better to buy. To help buyers make their choice, this list has been compiled. The rating includes the best fuel filter companies. The models are distinguished by their reliability and quality.
