Caution: Provide additional support when a vehicle is on a hoist:

Notice: 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.

Notice: Do not bend the fuel tank straps as this may damage the straps.

Notice: 

Notice: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.

Important: Do not attempt to repair sections of nylon fuel pipes. If the nylon fuel pipes are damaged, replace the pipes.

Important: Always maintain cleanliness when servicing the fuel system components.

1. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief .
2. Drain the fuel tank. Refer to Fuel Tank Draining .

Caution: Provide additional support when a vehicle is on a hoist:

•	Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

•	Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
3. Raise the vehicle.



4. Loosen the fuel filler hose clamp (1) at the fuel tank (3).



5. Remove the fuel filler hose from the fuel tank.



6. Remove the quick-connect fittings at the fuel tank. Refer to Plastic Collar Quick Connect Fitting Service .
7. Remove the EVAP pipe from the connection at the front of the fuel tank.
8. Remove the rubber exhaust pipe hangers and allow the exhaust system to drop slightly.



9. With the aid of an assistant, support the fuel tank and remove the attaching bolts which retain the fuel tank straps.



10. Disconnect the EVAP pipes (2)from the rear of the fuel tank.
11. Disconnect the EVAP pipe from the fuel limiter vent valve (3).
12. Disconnect the filler neck EVAP pipe at the rear of the fuel tank.
13. Remove the fuel tank from the vehicle and place the fuel tank on a suitable work area.
14. If the fuel tank is not being replaced, go to the installation procedure.



15. Remove the following components from the fuel tank:

•	The fuel feed assembly

•	The fuel return assembly

•	The EVAP pipe assembly

•	The insulator clips

•	The fuel limiter vent valve. Refer to Fill Limiter Vent Valve Replacement .




16. Remove the insulator pads from the fuel tank. Note the location of the insulator pads for installation.

1. Install the insulator pads on the fuel tank.



2. Install the following components to the fuel tank:

•	The fuel limiter vent valve. Refer to Fill Limiter Vent Valve Replacement .

•	The fuel fuel sender assembly. Refer to Fuel Sender Assembly Replacement .

•	The fuel feed assembly

•	The fuel return assembly

•	The EVAP pipe assembly

•	The insulator clips




3. With the aid of an assistant, position and support the fuel tank.
4. Connect the EVAP pipes to the rear of the fuel tank.
5. Connect the EVAP pipe to the fuel limiter vent valve.
6. Connect the fuel filler EVAP pipe at the rear of the fuel tank.

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.

7. Install the fuel tank strap attaching bolts.

Tighten
Tighten the bolts to 47 N·m (35 lb ft).




8. Install the quick-connect fittings at the fuel tank. Refer to Metal Collar Quick Connect Fitting Service .
9. Connect the EVAP pipe at the front of the fuel tank.



10. Connect the fuel tank filler hose to the fuel tank.



11. Ensure filler hose (4) is fully seated on fuel tank port (2).
12. Ensure the clamp (1) is properly located on the tank port between the bead (5) and the tank (3).

Tighten
Tighten the hose clamp to 2.5 N·m (22 lb in).

13. Install the rubber exhaust pipe hangers.
14. Inspect the fuel and EVAP pipes, making sure they were not kinked or damaged during removal and installation.
15. Lower the vehicle.
16. Remove the fuel filler cap and add fuel to the vehicle.
17. Install the fuel tank filler cap.
18. Perform the following procedure to inspect for leaks:

18.1.
