Fuel Pump Module And Locking
3. Part of Fuel Tank Removal Procedure: Disconnect EVAP line at pump module; disconnect wiring harness connector at pump module; disconnect
fuel line from fuel filter fitting.
4. Rotate fuel filter until its fitting is pointed towards center of pump module.
5. A metal lockring is used to secure fuel pump module to fuel tank. Six metal fingers are molded into the plastic fuel tank. The fingers are used to
retain lockring to fuel tank. A rubber gasket is used as a seal between module and fuel tank.
6. Before removing lockring, apply a small amount of engine oil to 6 fingers where fingers meet lockring (to act as a lubricant).
7. Remove (rotate) lockring counterclockwise using a brass or bronze drift punch and a hammer. This must be done while slightly prying back on
lock tab.
8. Remove lockring and pump module from fuel tank.
INSTALLATION
CAUTION: Whenever fuel pump module is serviced, the module gasket must be replaced.
1. Using a new gasket, position fuel pump module into opening in fuel tank. Be sure rubber gasket remains in place. Rotate pump module assembly
until module is positioned as shown in. This step must be followed to prevent float/float rod from contacting sides of fuel tank.
2. Before installing lockring, apply a small amount of engine oil to 6 fingers where fingers meet lockring (to act as a lubricant).
3. Position lockring over top of fuel pump module. Tighten finger tight.
4. Install (rotate) lockring clockwise using a brass or bronze drift punch and a hammer. Continue rotating lockring until 6 fingers drop into 6 finger
locks and lock tab falls into lockring notch.
