NOTE: 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.

Remove fuel tank. Refer to FUEL TANK .
Disconnect fuel feed and return lines from filter/pressure regulator.
Disconnect fuel pump vapor line from fuel tank vent pipe.
NOTE: To prevent retainer damage, do not attempt to remove the retainer with a 12 in. or shorter ratchet/breaker bar.
Use the Fuel Tank Lock Ring Remover SA9156E and remove the fuel pump module retaining ring. A 1/2 in. breaker bar (approximately 18 inches long) will easily loosen and remove the lock ring.
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 90° clockwise until the fuel lines are facing the 1 o'clock position (12 o'clock is front of tank).
