Hello & Welcome,

 

Can you tell us what Engine Size you have in your vehicle?

If you have the VIN handy (or the 8th character), that would be good.

 

Thanks

Hi again,

 

Here is the procedure to replace the filter. The last drawing shows the location, which is on a cross member just in front of the fuel tank.

 

Fuel Filter Replacement

Removal Procedure

Important

There is no service interval for fuel filter replacement. Only replace the fuel filter if the filter is restricted. Inspect the fuel tank internally and clean the fuel tank if you find a restricted fuel filter.

 

  1. Relieve the fuel system pressure.
  2. Raise the vehicle.

  3. Disconnect the fuel filter fitting using a back-up wrench.

  5. Remove the fuel filter.

Installation Procedure


    graphic

  1. Remove the protective caps from the new fuel filter.
  2. Install the fuel filter (2) in the same position as the old fuel filter.
  3. Connect the fuel filter quick connect fitting.

    Notice

    Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

     

  4. Connect the fuel filter fitting (3) using a back-up wrench. Tighten

    Tighten the fuel filter fitting to 27 N·m (20 lb ft).

  5. Lower the vehicle.
  6. Connect the negative battery cable.
  7. Inspect for fuel leaks using the following procedure:
    1. Turn ON the ignition, with the engine OFF for 2 seconds.
    2. Turn OFF the ignition for 10 seconds.
    3. Turn ON the ignition, with the engine OFF.
    4. Inspect for fuel leaks.

I hope this helps. Please let me know if you need more information.

 

Take Care, Greg A.
