The fuel filter is connected in series between the fuel pump and the inlet of the throttle body. The function of the fuel filter is to filter the iron oxide contained in the fuel. The structure of the fuel filter is composed of an aluminum shell and a bracket with stainless steel inside. To increase the circulation area. EFI filters are not compatible with carburetor filters. Because the EFI filter often withstands fuel pressure of 200-300KPA, the pressure strength of the filter is generally required to be above 500KPA, while the oil filter does not need to reach such a high pressure.
There are various impurities in gasoline, and some dirt will precipitate in the fuel tank for a long time. The above reasons will affect the quality of gasoline. The function of the petrol grid is to filter the above impurities. The gasoline in the fuel tank is filtered by the petrol grid to reach the combustion chamber of the engine, and its clean purity can be effectively guaranteed.
