Check the lock ring for flatness.
12. Place the lock ring on a flat surface. Measure the clearance between to lock ring and the flat surface using a feeler gauge at 7 points.
13. If the warpage is less than 0.41 mm (0.016 in), the lock ring does not require replacement.
14. If the warpage is greater than 0.41 mm (0.016 in), the lock ring must be replaced.
15. If only replacing the module, remove the fuel level sensor. Refer to Fuel Level Sensor Replacement (See: Computers and Control Systems/Fuel
Level Sensor/Service and Repair).
Installation Procedure
1. Install a NEW fuel pump module seal onto the fuel tank.
2. If installing only the module, install the fuel level sensor. Refer to Fuel Level Sensor Replacement (See: Computers and Control Systems/Fuel
Level Sensor/Service and Repair).
Note: The reservoir must be tipped slightly during installation to avoid bending the fuel level sensor float arm.
3. Tilt the module toward the rear of the fuel tank to allow the fuel level sensor float arm to clear the tank opening. Install the module into the fuel
tank.
4. Lower the module assembly into the tank. Ensure that the fuel level sensor harness connector is positioned properly.
5. Install the module lock ring over the module pipes and electrical harness, and into position on the top of the module.
