Working Principle Of Fuel Filter

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 oil device is composed of an aluminum shell and a stainless steel bracket. A high-efficiency filter paper is installed on the bracket. The filter paper is shaped like 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 resistance of the filter is generally required to reach 500KPA or more, and the carburetor filter does not need to reach such a high pressure.
