The quality of gasoline varies in different parts of China. However, different vehicle quality has different effects on fuel filter. The main function of fuel filter is to filter impurities in gasoline, so that the engine can use pure fuel. Therefore, the maintenance of fuel filter is also very important.

1、 Necessity of replacing fuel filter
Fuel filter can be divided into gasoline filter and diesel filter according to different fuels. Gasoline filter is mainly used for household vehicles, and gasoline filter is divided into internal and external fuel tank type.
The fuel filter works for a long time and reaches a certain life span with the increase of vehicle age and mileage, which will lead to weak acceleration, increased fuel consumption, increased noise, and reduced handling functions.

2、 How often should the fuel filter be replaced?
It is proposed to replace the fuel filter every 10000 km, and replace the fuel filter in the fuel tank every 40000~80000 km. There may be slight differences in the maintenance period between different car models. Please understand when your car needs to be replaced for maintenance through the "self maintenance" performance.
During major maintenance, the fuel filter is usually replaced at the same time as the engine oil, machine filter, and air filter.
The disassembly and replacement of the fuel filter is relatively complex, and it is strictly prohibited to operate it manually. It needs to be operated and installed by professional personnel from a special store.

3、 Precautions for purchasing fuel filter
1. Before purchasing goods, please be sure to verify the vehicle model, displacement, and other information to ensure that you have purchased the correct model of accessories. You can check the car maintenance manual and also apply the "self-service maintenance" performance of the car maintenance website.
2. During major maintenance, fuel filter is usually replaced with engine oil, engine filter and air filter at the same time.
3. Choose high-quality fuel filters. Poor quality fuel filters often result in poor fuel supply, insufficient vehicle power, and even extinguishing fires. Impurities are not filtered, and over time, the oil circuit and fuel injection system will also be corroded and damaged.
4. When you feel a significant decrease in speed, poor acceleration, and weak driving, it is important to consider that the fuel filter may have been blocked and need to be tested on time.
These are the maintenance precautions of the fuel filter summarized by me. I hope they will be helpful to you. When you service the car, don't forget to take care of the fuel filter. Don't ignore its role because it is relatively small. If it has an accident, the car will still fail to run. Take care of the car as yourself, so that you can drive more comfortably.
