CAUTION Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do NOT allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.
There are two types of fittings used on fuel filter connections. The banjo fitting or union bolt type uses a bolt and two washers to prevent leakage between an eyelet and the filter. The flare fitting type uses no washers or bolts. It uses a thread interference pattern to make a tight connection.

1. Unbolt the retaining screws and remove the protective shield (if equipped) for the fuel filter.
2. Place a pan under the delivery pipe (large connection) to catch the dripping fuel and SLOWLY loosen the banjo fitting bolt or flare fitting at the bottom of the filter to bleed off the fuel pressure.

CAUTION To avoid personal injury, remember that the fuel system is under pressure. Release pressure slowly and contain spillage. Wear eye protection and observe no smoking/no open flame precautions. Have a dry powder fire extinguisher within arm's reach at all times.

1. Remove the banjo bolt or flare fitting and drain the remaining fuel.
2. Disconnect and plug the inlet line.
3. Unbolt and carefully remove the fuel filter. It may still contain some fuel.

To install:
When tightening the fuel line bolts to the fuel filter, you must use a torque wrench. The tightening torque is very important, as under or over tightening may cause fuel leakage. Insure that there is sufficient clearance between the fuel filter, lines and any other parts.

1. Coat the flare or banjo bolt threads along with the copper washers lightly with engine oil. Always use new washers.
2. Hand tighten the inlet line to the fuel filter.
3. Install the fuel filter then tighten the banjo type bolt to 22 ft. lbs. (29 Nm) or the flare fitting on the fuel pump side to 17 ft. lbs. (24 Nm) and all others to 22 ft. lbs. (30 Nm).

WARNING The fuel pump builds high pressure within the lines. If new gaskets are NOT used, a high-pressure leak may spray fuel onto the engine or other hot surface.

1. Run the engine for a few minutes and check for any fuel leaks.
2. Install the protective shield if removed.

The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.

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.

To install:

I hope helps whit this (remember rated this help) Good luck.

The fuel filter is under the car next to the fuel pump reservoir and looks like a large, metal container. Arrows point the direction of fuel flow through the filter. Banjo type fittings with copper gaskets connect the fuel lines to the filter. Always replace these gaskets any time the fittings are loosened.



Follow the replacement procedure below to change out the existing filter.

1. Relieve the fuel system pressure.

2. Raise and safely support the rear of the vehicle. Have a pan ready to catch the fuel that will run out of the reservoir.

3. Have a rag handy and wear safety glasses when loosening the fittings. The system will be under pressure and fuel will be sprayed.

4. Hold the filter with a 19mm or 22mm wrench and loosen the fittings with a 17mm wrench. Wrap the filter and wrenches with a rag to contain any pressurized fuel. Have the catch pan ready.

5 Disconnect the fuel lines, loosen the mounting bracket and remove the filter.

6 Install the new filter but do not tighten the mounting bracket yet.

7 Make sure all fittings and sealing surfaces are clean. Install the banjo bolts with new copper gaskets and torque to 14 ft. lbs. (20 Nm).

Removal & Installation Two types of filters are used, depending on the vehicle. Both are located between the rear axle and the fuel tank.

1. Disconnect the negative battery cable.
   
2. Unscrew the cover box.
