When Should the Car Fuel Filter Be Replaced?

[LaPenelope]

The external fuel filter should generally be replaced every 20,000 to 30,000 kilometers. The internal fuel filter should generally be replaced every 50,000 to 70,000 kilometers. Below are detailed explanations about external and internal fuel filters: 1. External fuel filter: The external fuel filter is located outside the fuel tank, making its replacement relatively simple. Therefore, the external fuel filter can be replaced more frequently. It is important to note that the arrow on the filter housing should point toward the front of the car. 2. Internal fuel filter: The internal fuel filter is located inside the fuel tank, making its replacement more complex and difficult. The internal fuel filter integrates the fuel pump, fuel level sensor, and pressure valve. Mistakes during the replacement process may damage the pump housing. Therefore, the internal fuel filter should not be replaced frequently.
