Relieve fuel system pressure. Refer to Fuel Pressure Release .
Disconnect the negative battery cable.
Raise the vehicle on a hoist. NOTE: Extreme care must be used when lowering the fuel tank. The fuel sender is made of plastic and may be damaged when lowering the fuel tank.
Remove the fuel tank.
Remove the sender unit and pump by turning the cam lock counterclockwise using tool J36608.
Remove the fuel pump from the sending unit by performing the following steps:
6.1. Pull the fuel pump up into the attaching hose while pulling outward from the bottom support.
6.2. Do not damage the rubber insulator or the strainer.

Inspect the fuel pump attaching hose for signs of deterioration.
Inspect the rubber sound insulation at the bottom of the pump.
Inspect the strainer.

Install the fuel pump assembly into the attaching hose. NOTE: Do not fold or twist the strainer when installing the sending unit. This action restricts fuel flow.
Install the sending unit and fuel pump assembly into the fuel tank.
Insert a new O-ring seal.
Install the cam lock assembly.
Turn the cam lock clockwise in order to lock it.
Install the fuel tank.
Connect the negative battery cable.
Check the system for leaks.
