Reasons why the fuel filter needs to be replaced:
1. Gasoline is refined from crude oil through a complex process, and then transported to various refueling stations through special channels, and finally delivered to the owner's fuel tank;
2. In this process, impurities in gasoline will inevitably enter the fuel tank. With the prolongation of use time, impurities will also increase. The above reasons will affect the quality of gasoline;
3. The function of the fuel filter is to remove the iron oxide, dust and other solid debris 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.

1. 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 debris 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;
2. The structure of the fuel burner consists of an aluminum shell and a bracket with stainless steel inside. The bracket is equipped with a high-efficiency filter paper, which is in the shape of a chrysanthemum to increase the flow area;
3. The EFI filter cannot be used in common with the carburetor filter. Since the EFI filter often bears the fuel pressure of 200-300KPA, the compressive strength of the filter is generally required to reach more than 500KPA, while the carburetor filter does not need to reach such a high pressure;
