5. Clean all the fuel filter connections and the surrounding areas before disconnecting the fuel pipes in order to avoid possible contamination of the fuel system.
6. Disconnect the threaded fittings from the fuel filter.
7. Cap the fuel pipes in order to prevent possible fuel system contamination.
8. Slide the fuel filter from the bracket.
9. Inspect the fuel pipe O-rings for cuts, nicks, swelling, or distortion. Replace the O-rings if necessary.

1. Slide the fuel filter into the bracket. Remove the caps from the fuel pipes.
2. Connect the threaded fittings to the fuel filter. Tighten the fittings to 18 ft. lbs. (25 Nm).
3. Lower the vehicle.
4. Tighten the fuel filler cap.
5. Connect the negative battery cable.
6. Turn the ignition ON for 2 seconds.
7. Turn the ignition OFF for 10 seconds.
8. Turn the ignition ON .
9. Inspect for fuel leaks.

1. Disconnect the battery ground cable.
2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
   
3. Remove the fuel tank assembly.
4. Clean the area around the fuel filter/regulator.

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
3. Remove and discard the mounting gasket below the filter/regulator.
4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
3. Apply a small amount of clean engine oil to the O-rings.
4. Install a new gasket on top of the fuel pump module.
5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
9. Install the fuel tank assembly.
10. Connect the negative battery cable.

1. Drain fuel tank and remove the tank.
2. Thoroughly wash and clean area around pump module to prevent contaminants from entering tank.
3. The plastic fuel pump module locknut is threaded onto fuel tank. Install special tool #6856 to fuel pump module locknut and remove locknut. The fuel pump module will spring up when locknut is removed.
4. Remove the module from fuel tank.

1. Thoroughly clean locknut threads and mating fuel tank threads. Use a solution of soap and water. Do not use carburetor cleaner to clean threads.
2. Using new gasket, position fuel pump module into opening in fuel tank.
3. Apply clean water to locknut threads.
4. Position locknut over top of fuel pump module.
5. Rotate module until arrow is pointed toward front of vehicle (12 o'clock position). This step must be done to prevent float/float rod assembly from contacting sides of fuel tank.
6. Install special tool #6856 to the locknut.
7. Tighten the locknut to 55 ft-lb (74 Nm).
8. Rotate fuel filter/fuel pressure regulator until its fitting is pointed to 10 o'clock position.
9. Install the fuel tank.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Properly relieve the fuel system pressure.
3. Drain and remove the fuel tank from the vehicle
4. Remove or disconnect the following:
   Negative battery cable Quick-connect fittings at the fuel pump Fuel pump locking nut with a Fuel Pump Spanner Wrench J 39348 Fuel pump assembly from the fuel tank and discard the O-ring

1. Install or connect the following:
   New O-ring on the fuel tank Fuel pump into the fuel tank making certain not to fold or twist the strainer and that it does not interfere with the full travel of the float arm Fuel pump locking nut with the scanner tool Quick-connect fittings at the fuel pump Fuel tank and fill the tank Negative battery cable
2. Prime the fuel system as follows:
   1. Turn the ignition switch ON for two seconds.
   2. Turn the ignition switch OFF for 10 seconds.
   3. Turn the ignition switch ON and checks for leaks. Repair if necessary.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Properly relieve the fuel system pressure.
3. Disconnect the negative battery cable.
4. Drain the fuel tank into an approved container.
   WARNING Do not attempt to straighten any kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.
   WARNING Do not attempt to repair sections of nylon fuel pipes. If the nylon fuel pipes are damaged, replace the pipes.
5. Raise the vehicle.

6. Disconnect the fuel supply pipe (5) quick-connect fitting.
7. Disconnect the evaporative emission (EVAP) purge pipe (6) quick connect fitting at the EVAP canister.
8. Loosen the fuel tank filler pipe hose clamp.
9. Disconnect the fuel tank filler from the fuel tank.
10. Disconnect the vapor recirculation pipe from the filler tube.
11. Remove the fuel tank shield.
12. With the aid of an assistant, support the fuel tank.

17. Disconnect the fuel sender electrical connections (3).
18. Clean all of the fuel pipe connections, all of the hose connections, and all of the areas surrounding the connections before disconnecting the connections in order to avoid possible contamination of the fuel system.
19. Disconnect the fuel supply pipe quick-connect fitting (4) at the fuel sender assembly.
20. Disconnect the evaporative emission (EVAP) pipe quick-connect fittings (5, 6) at the fuel sender assembly.
    CAUTION Do NOT use impact tools. Significant force will be required to release the lock ring. The use of a hammer and screwdriver is not recommended. Secure the fuel tank in order to prevent fuel tank rotation.

1. Properly relieve the fuel system pressure.
   
2. Disconnect the negative battery cable.
   
3. Raise and safely support the vehicle.
   
4. Place a drain pan underneath the fuel filter to catch any spilling fuel that will result from disconnecting the fuel lines.
   

1. Remove the fuel filter mounting bolt and remove the fuel filter from the fuel tank.
   

1. Install the fuel filter on the top of the fuel tank and tighten the mounting bolt.
   
2. The fuel supply tube (to chassis fuel line), return tube (to pump module) and fuel supply (to fuel filter) tube are permanently attached to the fuel filter. The quick-connect fitting ends of the fuel supply and return tubes are of different sizes.
   
3. Apply a light coating of 30W engine oil to the nipples of the fuel filter.
   
4. Push the quick-connect fitting over the fuel line until the retainer seats and clicks into place. Be sure the retainer tabs have locked into the case of the fitting.
   
5. If necessary, raise the fuel tank and tighten the fuel tank strap bolts.
   
6. Lower the vehicle. Start the engine and check for leaks.
