  1. Remove the quick-connect fittings at the fuel sender assembly
  2. Remove the electrical connector at the fuel sender.
  3. Remove the fuel sender retaining ring using the J 39765 Fuel Sender Spanner Wrench. Important: When removing the modular fuel sender assembly from the fuel tank, the reservoir bucket on the fuel sender assembly is full of fuel. The modular fuel sender assembly must be tipped slightly during removal in order to avoid damage to the float. Place any remaining fuel into an approved container once the modular fuel sender assembly is removed from the fuel tank. The modular fuel sender assembly will spring-up when the locking ring is removed.
  4. Pull the modular fuel sender straight up while pumping the fuel from the reservoir.
  5. Clean the fuel sender assembly O-ring sealing surfaces.
  6. Inspect the fuel sender assembly O-ring sealing surfaces.

Installation Procedure

  1. Position the new fuel sender assembly O-ring on the fuel tank. Important: Care should be taken not to fold over or twist the fuel pump strainer when installing the fuel sender assembly, as this will restrict fuel flow. Also, assure that the fuel pump strainer does not block full travel of float arm.
  2. Install the fuel sender assembly and the fuel sender assembly retainer cam using the J 39765 Fuel Sender Spanner Wrench.
  3. Install the quick-connect fittings at the fuel sender assembly.
  4. Install the negative battery cable.
  5. Inspect for leaks.
  1. Install the fuel sender access panel.
  2. Reposition the trunk liner.
