REMOVAL PROCEDURE

CAUTION: Fuel Vapors can collect while servicing fuel system parts in enclosed areas such as a trunk. To reduce the risk of fire and increased exposure to vapors:
Use forced air ventilation such as a fan set outside of the trunk.
Plug or cap any fuel system openings in order to reduce fuel vapor formation.
Clean up any spilled fuel immediately.
Avoid sparks and any source of ignition.
Use signs to alert others in the work area that fuel system work is in process.

NOTE: Clean all of the following areas before performing any disconnections in order to avoid possible contamination in the system:
The fuel pipe connections
The hose connections
The areas surrounding the connections

IMPORTANT:
For rear compartment (trunk) accessible fuel sender assemblies, completely remove the rear compartment carpet before removing the fuel sender access panel.
Always replace the fuel sender O-rings when reinstalling the fuel sender assembly.
The modular fuel sender assembly will spring-up when the snap ring is removed.
Always maintain cleanliness when servicing fuel system components.
1. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief Procedure. See: Fuel Pressure Release > Procedures > Fuel System Pressure Relief
2. Remove the rear compartment trim panel.
3. Remove the nuts retaining the fuel sender access panel.
4. Remove the fuel sender access panel.
5. Disconnect the fuel tank pressure sensor electrical connector.
6. Disconnect the fuel sender electrical connector.
7. Clean the fuel pipes, and fuel sender assembly to prevent possible fuel contamination during removal.
8. Disconnect the quick-connect fittings at the fuel sender assembly.
9. Remove the fuel sender retaining snap ring.
10. Remove the modular fuel sender assembly.
11. Clean the fuel sender assembly O-ring sealing surfaces.
12. Inspect the fuel sender assembly O-ring sealing surfaces.

INSTALLATION PROCEDURE

NOTE: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.

Do not repair sections of fuel pipes.

IMPORTANT:
Care should be taken not to fold over or twist the fuel pump strainer when installing the fuel sender assembly, as this will restrict fuel flow. Also, assure that the fuel pump strainer does not block full travel of float arm.
Be sure that the fuel sender assembly retaining snap ring is fully seated within the tab slots on the fuel tank.
1. Position the new fuel sender assembly O-ring on the fuel tank.
2. Install the fuel sender assembly into the fuel tank.
3. Install the fuel sender assembly retaining snap ring, while holding the fuel sender in place.
4. Connect the fuel sender electrical connector.
5. Connect the fuel tank pressure sensor electrical connector.
6. Connect the quick-connect fittings at the fuel sender assembly.
7. Install the fuel filler cap.
8. Connect the negative battery cable.
9. Inspect for leaks using the following procedure:
9.1. Turn ON the ignition, for 2 seconds.
9.2. Turn OFF the ignition, for 10 seconds.
9.3. Turn ON the ignition.
9.4. Inspect for leaks.
10. Install the fuel sender access panel.

NOTE: Refer to Fastener Notice in Service Precautions.

11. Reinstall the nuts retaining the fuel sender access panel.

Tighten
Tighten the fuel sender access panel nuts to 10 N.M (88 lb in)

12. Install the rear compartment trim panel.
13. Install the spare tire, the jack, and the spare tire cover.

It's under the hood in the junction block (top). Here is a picture of it. You will see that is has both the fuse and the relay.

There is no fuel pump cut off switch on your vehicle. There is a fuel pump relay that is most likely in the underhood fuse block.

Go through the back seat and lift the trunk carpet. I think there is an access panel back there to get at the fuel pump. Other wise you will have to drop the fuel tank.

No, you can access it from inside the trunk. Under the carpet is a plate, unbolt it and you will see the top of the sending unit. Post back with any other questions.
