REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
The vehicles covered in this guide are equipped with Quick Connect fuel fittings. For more information regarding these fittings, please refer to Fuel System of this guide.
An inline filter can be found in the fuel feed line attached to the rear crossmember of the vehicle.
- Properly relieve the fuel system pressure as outlined in Fuel System .
- Raise and safely support the vehicle with jackstands.
- Grasp the filter and nylon fuel line fitting on the tank-to-filter line. Twist the quick-connect fitting 1 / 4 or a turn in each direction to loosen any dirt within the fitting. Use compressed air to blow out the dirt from the fittinge at the end of the fuel filter.
- Detach the quick-connect fitting by pushing inward toward the filter and grasping the plastic tab around the connector and pull apart. If additional assistance is required to disconnect the fitting, tool J 38778 or equivalent can be placed between the filter and the fitting release mechanism to carefully force the two apart. Be careful not to bend the special tool.
Always use a back-up wrench anytime the fuel filter ie removed or installed.
- Using a backup wrench (where possible) to prevent overtorquing the lines or fittings, loosen and disconnect the feed line from the filter. Be sure to position a rag in order to catch any remaining fuel which may escape when the fittings are loosened.
- Remove the fuel filter from the retaining bracket.
- Before installing a new filter, apply a few drops of clean engine oil to the male tube end of the filter. This will ensure proper attachment and prevent a fuel leak.
- Position the filter into the retaining bracket with the directional arrow facing away from the fuel tank, towards the throttle body.
The filter has an arrow (fuel flow direction) on the side of the case, be sure to install it correctly in the system, the with arrow facing away from the fuel tank.
- Push the connectors on the quick-connect fitting together to cause the retaining tabs/fingers to snap into place. Pull on both ends of the connection to be sure they are secure.
- Connect the fuel feed line to the filter, then tighten, using a backup wrench to prevent damage, to 20-22 ft. lbs. (27-30 Nm).
- Carefully lower the vehicle.
- Connect the negative battery cable and tighten the fuel filler cap, then start the engine and check for leaks.
