Fuel Pump


Removal & Installation

Primary Module

NEW fuel tank module seals are necessary each time the fuel tank module is serviced. Obtain NEW seals for both the primary and secondary modules prior to beginning this service procedure.

Whenever fuel line fittings are loosened or removed, wrap a shop cloth around the fitting and have an approved container available to collect any fuel.

Clean all fuel pipe and hose connections and surrounding areas before disassembling to avoid possible contamination of the fuel system. Spray the fuel pump module cam-lock ring tang with penetrating oil prior to attempting removal.

  1. Remove the fuel tank.
  3. Remove the secondary fuel pump module.
  5. Disconnect the electrical connectors from the primary fuel pump module and fuel tank pressure sensor.
    Avoid damaging the lock ring. Use only tool J-45722 to prevent damage to the lock ring.

    Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

    Do NOT use impact tools. Significant force will be required to release the lock ring. The use of a hammer and screwdriver is not recommended. Secure the fuel tank in order to prevent fuel tank rotation.

  7. Use tool J 45722, or equivalent and a long breaker-bar in order to unlock the fuel sender lock ring. Turn the fuel sender lock ring in a counterclockwise direction.

    To prevent bending of the sending unit float arm during removal, lift the pump module up slightly to disengage the orientation tabs in the tank and rotate the module 45 degrees.

  11. Remove the primary fuel pump module assembly.
    Always replace the fuel pump module-to-tank seal, O-ring, when the fuel pump module is removed.
