How often to replace fuel filter?

The fuel filter is recommended to be replaced every 10,000 kilometers, and the fuel tank is replaced with a fuel filter of 40,000 to 80,000 kilometers. However, the maintenance period between different models may be slightly different. When doing major maintenance on the car, the fuel filter generally needs to be replaced at the same time as the engine oil, engine filter, and air filter.
As the age of the vehicle increases, the mileage increases, and the fuel filter works for a long time and reaches a certain life cycle, which will cause the vehicle to speed up weakly, reduce handling performance, increase noise, increase fuel consumption, and even accelerate flameout.
Choose a high-quality fuel filter, because inferior fuel filters often cause poor fuel supply, insufficient vehicle power or even flameout; if impurities are not filtered, the oil circuit and fuel injection system will corrode and damage over time.
When you feel that the vehicle speed is significantly reduced, the engine is not accelerating poorly, and the vehicle is running weak, you should think that the fuel filter may have been blocked, and you must check it in time.
The filter has an arrow mark on the inlet and outlet ports. Do not install it backwards when replacing it. After replacing the fuel filter, pay attention to the seal of the interface and be alert for oil leakage.
