The fuel filter is generally between 100-300 yuan, and it is replaced once every 20,000 kilometers:
1. The gasoline filter belongs to a kind of fuel filter. The fuel filter includes both the gasoline filter and the diesel filter. Therefore, for gasoline vehicles, the fuel filter is the gasoline filter element;
2. Filter out harmful particles and water in the engine fuel gas system to protect the oil pump nozzle, cylinder liner, piston ring, etc., reduce wear and avoid blockage;
3. 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;
4. When the engine is working, the fuel enters the sedimentation cup of the gasoline filter through the oil inlet pipe under the action of the gasoline pump. As the volume becomes larger and the flow rate becomes smaller at this time, the denser water and impurity particles will settle at the bottom of the cup, the impurities lighter than the oil will flow to the filter element with the fuel, and the clean fuel will penetrate into the inside of the filter element from the pores of the filter element, and then flow out through the oil pipe.

How to replace the fuel filter:
1. Open the fuel tank cap;
2. Remove the fuel pump fuse from the engine fuse box;
3. Start the engine and make the engine stall, and then turn the engine crankshaft for 10 seconds;
