The gasoline filter of a gasoline engine is located on the outlet side of the fuel transfer pump, and the working pressure is relatively high, and a metal casing is usually used.

The filter element of the gasoline filter mostly uses filter paper, and there are also gasoline filters that use nylon cloth and polymer materials. The main function of the gasoline filter is to filter out impurities in the gasoline.

 

 

The function of the fuel filter is to prevent particulate matter, water and impurities in the fuel, and to ensure that the precision parts of the fuel system are protected from wear and other damage.

If the gasoline filter is dirty or clogged. In-line filter paper gasoline filter: The gasoline filter is inside this type of gasoline filter. The folded filter paper is connected to the two ends of the plastic or metal filter. After the dirty oil enters, it passes through layers of filter paper from the outer wall of the filter. After filtering, it reaches the center and clean fuel flows out.

 

 

The fuel filter is connected in series on the pipeline between the fuel pump and the fuel inlet of the throttle body. The function of the fuel filter is to remove the iron oxide, dust and other solid impurities contained in the fuel to prevent the fuel system from clogging (especially the fuel injector). Reduce mechanical wear, ensure stable engine operation, and improve reliability. The structure of the fuel burner is composed of an aluminum shell and a stainless steel bracket. The bracket is equipped with high-efficiency filter paper, which is in the shape of a chrysanthemum to increase the circulation area. The EFI filter cannot be used in common with the carburetor filter. Because the EFI filter often bears the fuel pressure of 200-300KPA, the pressure strength of the filter is generally required to reach 500KPA or more, and the carburetor filter does not need to reach such a high pressure.
