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.

Notice: 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: Always maintain cleanliness when servicing fuel system components.




1. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief .
2. Remove the spare tire cover, the jack, and the spare tire.
3. Remove the rear compartment trim panel. Refer to Rear Compartment Trim Panel Replacement in Body Rear End.
4. Remove the nuts retaining the fuel sender access panel.
5. Remove the fuel sender access panel.
6. Disconnect the fuel tank pressure sensor electrical connector.
7. Disconnect the fuel sender electrical connector.
8. Clean the fuel pipes, and fuel sender assembly to prevent possible fuel contamination during removal.
9. Disconnect the quick-connect fittings at the fuel sender assembly. Refer to Metal Collar Quick Connect Fitting Service .




Important: The modular fuel sender assembly will spring-up when the snap ring is removed.

10. Remove the fuel sender retaining snap ring.
11. Remove the modular fuel sender assembly.
12. Clean the fuel sender assembly O-ring sealing surfaces.
13. Inspect the fuel sender assembly O-ring sealing surfaces.

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

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.

Important: Be sure that the fuel sender assembly retaining snap ring is fully seated within the tab slots on the fuel tank.

Important: Always replace the fuel sender O-rings when reinstalling the fuel sender assembly.

1. Position the new fuel sender assembly O-ring on the fuel tank.
2. Place the fuel sender assembly into the fuel tank.
3. Install the fuel sender assembly retaining snap ring, while holding the sender assembly 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. Refer to Metal Collar Quick Connect Fitting Service .
7. Install the fuel filler cap.
8. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
9. Inspect the fuel system for leaks by performing the following steps:

9.1.	Turn the ignition switch ON for 2 seconds.

9.2.	Turn the ignition switch OFF for 10 seconds.

9.3.	Turn the ignition switch ON.

9.4.	Inspect for fuel leaks.




10. Install the fuel sender access panel.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

11. Reinstall the (7) nuts retaining the fuel sender access panel.

Tighten
Tighten the fuel sender access panel nuts to 10 N·m (8 lb ft)

12. Install the rear compartment trim panel. Refer to Rear Compartment Trim Panel Replacement in Body Rear End.
13. Reinstall the spare tire, the jack, and the spare tire cover.
