Fuel Tank Replacement Right w/Auto Trans

Removal Procedure

Caution: Provide additional support when a vehicle is on a hoist in the following ways:

•	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.

1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure. Refer to the Fuel Pressure Relief .
3. Drain the fuel tanks. Refer to Draining Fuel Tanks .
4. Remove the mufflers. Refer to Muffler in Engine Exhaust.
5. Disconnect the fuel sender electrical connector.
6. Mark or identify each fuel pipe in order to aid in installing the pipes in their original positions.
7. Disconnect the fuel sender fuel feed pipe (1) (jet pump to left tank) and the fuel feed rear crossover pipe (2) (left tank to jet pump) at the fuel sender. Refer to Servicing Quick Connect Fittings .
8. Cap the fuel pipes in order to prevent possible fuel system contamination.



9. Remove the tank crossover hose (3).

Important: Do not disconnect the EVAP hose at the roll over valve.

10. Carefully disconnect the EVAP hose at the T-connector (2).



11. Remove the fuel tank strap/shield.
12. Remove the fuel tank.

Installation Procedure

Important: Always replace the fuel system hose clamps with the original equipment or parts that meet the GM specifications for those parts when replacing the clamps.

1. Install the fuel tank.
2. Install the fuel tank strap/shield.

Refer to the

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.
