How to Replace a Fuel Filter in a Ford Explorer. Keep the fuel system in your Ford Explorer in optimal condition by replacing the fuel filter every 30,000 to 40,000 miles. A clean fuel filter means clean fuel injectors and a clean fuel pressure regulator. Follow the instructions below to replace the filter on a Ford Explorer in under 45 minutes.
Begin by disconnecting the battery ground cable. Relieve the fuel system pressure by removing the fuel pump relay and then starting the engine. Let it idle until it stalls. Then, crank the engine for about 5 seconds to make sure the pressure has been released. Turn the ignition off.
Raise the vehicle and locate the fuel filter on the passenger side, under the door near the front wheel well. It is behind a curved shield called the fuel filter heat shield. Remove the bolts from that shield. Then, remove the nuts and the fuel filter shield.
Disconnect the quick release and spring lock couplings. Remove the fuel filter and any fuel line caps. Put the new filter in place and connect the quick-release and spring-lock couplings. Make sure you install the fuel pump relay. Reinstall the fuel filter heat shield and torque the bolts to 15 foot-pounds.
Lower the vehicle and reconnect the battery ground cable. Start your Ford Explorer, check for leaks, and fix any you find.
Don't disconnect the fuel lines until you let the pressure out of the fuel system. Before you start your Explorer, wipe up any fuel that may have spilled while replacing the filter.
