The fuel filter is located in the fuel feed line attached to the underbody, directly in front of the fuel tank.

  1. Relieve the fuel system pressure using the procedure outlined in Section 5. Also remove the fuel tank cap to relieve any residual fuel pressure in the tank which could force out fuel when the fuel lines are disconnected.
  2.  
  3. Raise the vehicle and safely support with jackstands.
  4.  
  5. Locate the fuel filter. Clean the area around the fittings, especially on the plastic quick-disconnect fittings. Use a bristle brush and/or compressed air, if available. A small amount of penetrating oil can be used on the steel threaded fitting only. This may be helpful, especially on high-mileage vehicles or where the filter has not been previously serviced.
  6.  
  7. Disconnect the fuel lines from the filter. The quick-connect end may have a dust cover over the end of the fitting. If used, slide the dust cover back over the fuel line to expose the fitting. For more information on servicing the quick-connect fitting, please refer to Section 5. To reduce fuel spillage, place a shop towel over the fuel lines before disconnecting.

To install:

  1. The replacement fuel filter should come with a new plastic connector retainer. Install the new plastic connector retainer on the filter inlet.
  2.  
  3. Slide the filter into the mounting bracket.
  4.  
  5. Apply a few drops of clean engine oil to the male pipe ends. This will ensure proper reconnection and help prevent possible fuel leaks. During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated. New O-rings are recommended and should come with the filter kit.
  6.  
  7. Using new O-rings, install the fuel lines to the filter. Pull on the quick-connect fitting end to verify that the locking tabs are properly engaged. If used, reposition the dust cover onto the fitting.
  8.  
  9. Tighten the steel fitting end of the filter. Use a backup wrench to keep the filter from turning. Torque the fittings to 22 ft. lbs. (30 Nm).
  10.  
  11. Lower the vehicle. Retighten the fuel filler cap.
  12.  
  13. Connect the negative battery cable. Start the engine and check for leaks.
