How many kilometers should the gasoline filter be replaced?

[Crystal]

Gasoline filters should be replaced approximately every 40,000 kilometers. The replacement method for gasoline filters is as follows: 1. Release the residual pressure in the fuel system; 2. Remove the grounding wire near the gasoline filter; 3. Place a basin under the filter; 4. Pull out the fuel inlet pipe and then remove the adjacent fuel outlet pipe; 5. Remove the old gasoline filter for replacement. Precautions for replacing the gasoline filter include: 1. Ensure the overall sealing of the air filter and cabin air filter; 2. Use the gasoline grade specified by the vehicle manufacturer. The gasoline filter, also known as the fuel filter, functions to remove iron oxide, dust, and solid impurities contained in the fuel, prevent fuel system blockages, reduce mechanical wear, ensure stable engine operation, and improve reliability.
