1. Ensure that the fuel level in the tank is less than 1/4 full. If necessary, drain the fuel tank to at least this level. Refer to Fuel Tank Draining .

Warning: Fuel supply lines will remain pressurised for a long period of time after the engine is shutdown. This pressure must be relieved before servicing the fuel system.

2. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
3. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
5. Remove the exhaust system. Refer to Exhaust Muffler Replacement : NB5 .
6. Remove the propeller shaft. Refer to Propeller Shaft Replacement .




Warning: Whenever fuel lines are removed, catch fuel in an approved container. Container opening must be a minimum of 300 mm (12 in) diameter to adequately catch the fluid.

Caution: Clean all fuel pipe connections and surrounding areas before disconnecting the fuel pipes to avoid contamination of the fuel system.

7. Place a suitable container under the fuel line connection in order to catch any dripping fuel.

14. Lower the front of the fuel tank (with shield), and pull the tank forward to clear the rear drive module.
15. If replacing the fuel tank, remove the fuel tank module assemblies. Refer to Fuel Tank Fuel Pump Module Replacement and Fuel Tank Fuel Pump Module Replacement - Secondary : Without .
16. If replacing the fuel tank, remove the heat shield, hoses and wiring harness and transfer to the new tank.

1. If previously removed, install the fuel tank module assemblies. Refer to Fuel Tank Fuel Pump Module Replacement and Fuel Tank Fuel Pump Module Replacement - Secondary : Without .




Note: Be careful to clear the fuel tank strap studs.

2. Using a suitable adjustable jack, install the fuel tank heat shield and fuel tank assembly to the vehicle.

Caution: Refer to Fastener Caution in the Preface section.

3. Install the fuel tank straps and the fuel tank strap-to-body nuts and tighten to 20 N·m (15 lb ft).



4. Connect the fuel tank electrical connector and install the electrical connector retainer to the rear frame.
5. Connect the EVAP vent, and fresh air hoses to the fuel tank.
6. Connect the fuel filler tube to the fuel tank. Tighten the fuel filler tube clamp to 5 N·m (44 lb in).



7. Connect the chassis fuel supply line (2) to the fuel tank.
8. Install the evaporative emission canister . Refer to Evaporative Emission Canister Replacement .
9. Install the propeller shaft. Refer to Propeller Shaft Replacement .
10. Install the exhaust system. Refer to Exhaust Muffler Replacement : NB5 .
