Replacing the fuel filter every 30,000 to 40,000 miles will keep the fuel system in your Jeep Grand Cherokee in good shape. A clean fuel filter helps maintain the fuel injectors and the fuel pressure regulator. Follow these instructions to replace the fuel filter in a Jeep Grand Cherokee manufactured between 2002 and 2004.
Instructions
- 1
Disconnect the negative battery cable and then remove the fuel tank cap to release fuel tank pressure. Remove the fuel pump relay from the PDC. Start the engine and allow it to run until it stops. Select any injector and unplug its connector.
2Connect a jumper wire from an injector terminal to the positive battery terminal. Then, connect the other jumper wire to the other battery terminal. Briefly touch the end to the negative battery terminal.
3Locate the fuel filter/pressure regulator near the front of the fuel tank, mounted to the body above the rear axle. Disconnect the fuel supply, fuel return and fuel pressure lines. Remove the mounting bolts and then the fuel filter/pressure regulator.
4Attach the new fuel filter/pressure regulator to the body and tighten the bolts to 30 in-lbs. Reconnect the fuel supply, fuel return and fuel pressure lines. Reconnect the negative battery cable. Start the engine of your Jeep Grand Cherokee and check for leaks.
