How to Replace a Fuel Filter in a Nissan Pathfinderby Contributor
The fuel filter in your Nissan Pathfinder screens out dirt and rust particles from the fuel. Some mechanics recommend that you replace the fuel filter every 30,000 to 40,000 miles to keep your fuel system clean, as even small pieces of debris could clog an injector and cause serious engine problems. Follow the instructions below to replace the fuel filter in a Nissan Pathfinder manufactured between 1996 and 2004.
Relieve the pressure from the fuel system by first removing the fuel pump fuse in the panel. Start the engine and allow it to run until it stalls. Let out any remaining fuel pressure by cranking the engine for a few seconds.
Disconnect the negative battery cable. Remove the fuel filter shield if there is one. Disconnect the fuel lines and then take the fuel filter out of the bracket.
Place the new fuel filter in the bracket. Reconnect the fuel lines and return the fuel shield to its appropriate position, if applicable.
Replace the fuel pump fuse and connect the negative battery cable when your repairs are complete. Start the engine of your Nissan Pathfinder and check for leaks. Repair any leaks you find.
- Always let the pressure out of the fuel system before you disconnect the fuel lines. Do this carefully so as not to spray fuel on your skin or eyes.
- Before starting your Nissan Pathfinder, make sure to wipe up any fuel that may have spilled on the vehicle while you were replacing the filter.
