Removing the fuel tank

To remove the fuel tank, you will need an assistant to support the tank during the process. Begin by installing the left-hand side of the fuel tank over the exhaust pipe. Then, raise the right-hand side of the tank into position inboard of the right-hand frame rail. Take care when feeding the fuel feed and return pipes, the EVAP vapour pipe, and the fuel pump module electrical harness over the rear axle. Install the right-hand fuel tank strap and strap bolts, followed by the left-hand fuel tank strap and strap bolts. Tighten the bolts to 18 ft. lbs. Once the tank is clear of the right-hand frame rail, remove the fuel tank down and toward the right-hand side of the vehicle.

Removing the fuel pump module assembly

To remove the fuel pump module assembly, you will first need to drain the fuel tank. You should then carefully lift the pump assembly out of the tank, twisting and rolling the assembly to manoeuvre the pump through the opening. You will likely spill some fuel, so have rags handy and keep the area well-ventilated.

If your fuel tank uses a one-piece module, disconnect the hoses before removing the cover. If your tank has a lock ring, you can pull off the top part, which is attached with wires to the bottom two parts. The bottom two parts are a cylindrical-shaped fuel pump that slides into a sleeve, and the sleeve is attached to the bottom of the tank.

If you have an integrated pump module, the fuel-level sending unit will likely be attached. This is a long lever with a float at the end. Be careful not to damage the fuel-level unit, which provides information to your fuel gauge. Remove the wiring plug from the fuel pump. Most newer vehicles use a plastic plug, but some older vehicles have threaded studs with ring terminals.

Before servicing the vehicle, refer to the Precautions Section.

To replace the fuel pump, first, have an assistant support the fuel tank during fuel tank and fuel tank strap installation. Begin to install the left-hand side of the fuel tank over the exhaust pipe. Raise the right-hand side of the fuel tank into position inboard of the right-hand frame rail. Use care in feeding the fuel feed and return pipes, the EVAP vapour pipe, and the fuel pump module electrical harness over the rear axle. Install the right-hand fuel tank strap and strap bolts. Install the left-hand fuel tank strap and strap bolts. Tighten the bolts to 18 ft. lbs. If the fuel tank only is to be replaced, remove the fuel pump module assembly from the fuel tank.
