How often should the built-in fuel filter be replaced?

[IrisLee]

The built-in fuel filter should be replaced every 20,000 kilometers. The method for replacing the automotive fuel filter is as follows: 1. Drive the car onto a lift and raise it to an appropriate position; 2. Remove the small protective panel on the right rear of the car to access the fuel filter; 3. Loosen the three clips above, remove the old filter, and replace it. The function of the fuel filter is to filter impurities in the gasoline, protect components such as the fuel pump, fuel injector, cylinder liner, and piston rings, reduce mechanical wear, prevent fuel system blockages, and ensure stable engine operation and improved vehicle safety. The effects of not replacing the fuel filter for a long time are: 1. Failure to replace the fuel filter can cause impurities to clog the fuel injector, leading to reduced power; 2. Cause poor fuel flow and increased fuel consumption; 3. Make it difficult to filter impurities in the gasoline, resulting in incomplete combustion and carbon deposits; 4. Severe clogging of the fuel filter can make the car difficult to start or unable to start.
