Fuel Pump Module: Installation

Fuel tank removal will be necessary for fuel pump module removal.

1. Thoroughly clean lock nut threads and mating fuel tank threads. Use a soap/water solution. Do not use carburetor cleaner to clean threads.
2. Using new gasket,  position fuel pump module into opening in fuel tank.
3. Apply clean water to lock nut threads.
4. Position lock nut over top of fuel pump module.
5. Rotate module until indexing arrow at top of module (Fig 1 ) is pointed toward rear of vehicle. Align arrow to tick mark on top of fuel tank. This step must be done to prevent float/float rod assembly from contacting sides of fuel tank.
