The fuel filter is connected in series between the fuel pump and the throttle body inlet port. The effect 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, which is composed of high efficiency filter paper, and the filter paper is chrysanthemum , To increase the circulation area. EFI filter can not be used with oil filter. Because the EFI filter often withstand 200-300KPA fuel pressure, so the filter pressure strength is generally required to reach more than 500KPA, and the oil filter is not necessary to achieve such a high pressure.
General gasoline there are a variety of impurities, long-term use of the tank will precipitate a certain amount of dirt, the above reasons will affect the quality of gasoline. The role of the gas grid is to filter the above impurities, the fuel tank through the gasoline cell filter to reach the engine combustion chamber, the clean purity can be effectively protected.
