The fuel filter assembly can be replaced once every 100,000 kilometers:
1. Gasoline filter assembly, it should be built-in. The built-in gasoline filter is assembled in the fuel tank with the fuel pump;
2. Usually, we only replace the gasoline filter. When replacing, remove the old gasoline filter from the gasoline pump assembly, replace it with a new one, and reassemble it with the gasoline pump and other components;
3. If you want to replace the gasoline pump assembly as a whole, you can also replace it, so the cost is relatively high.

Introduction of fuel filter:
1. There are three types of fuel filters: diesel filters, gasoline filters and natural gas filters. The function of the fuel filter is to prevent particulate matter, water and impurities in the fuel, and to ensure that the precise components of the fuel system are protected from wear and other damage;
2. 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, prevent the fuel system from clogging, especially the fuel injection nozzle, reduce mechanical wear, ensure the stable operation of the engine, and improve reliability;
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.
