How to Install a Fuel Pump on a 1994 Pontiac Bonneville

The Pontiac Bonneville is one of many vehicles where the fuel pump is contained within a module stored within the fuel tank. For the '94 model, you can install a pump within the module rather than replace the entire module. Just be sure to use extreme caution when working on the car's fuel system.

• 1

  Insert the fuel pump into the mounting bracket on the pump/sending unit module, then connect it to the electrical connector on the module

• 2

  Insert the fuel pump module into the mounting hole in the fuel tank. Make sure there is a fresh O-ring around the fuel tank's opening. Insert the module at an angle that won't damage its float or strainer.

• 3

  Install the module's lock ring onto the flange. Turn it clockwise to lock it in place. You might need to tap it with a brass punch and hammer.

• 4

  Raise the Bonneville's rear end onto jack stands using a floor jack.

• 5

  Raise the fuel tank into place on the car using either the floor jack or an assistant's help. Connect the two straps to hold the tank in place using their bolts and a wrench.

• 6

  Connect the fuel feed, return and vapor lines to the pump module using the quick-connect fittings or the hose clamps and pliers. Connect the electrical connector to the fuel pump/sending unit.

• 7

  Lower the car off the jack stands.

• 8

  Fill the fuel tank at the filler neck.
