How to replace the Fuel Level Sensor assembly on Buick LaCrosse?

The first step for Fuel Level Sensor replacement requires removal of the Fuel Tank. The first step is to disconnect both electrical connectors from the fuel sender module then handle the Fuel Level Sensor with care to prevent damaging the fuel pipe joints. You should remove fuel pipes from the fuel sender by using only the fuel sender lock ring wrench (J 45722) to protect the lock ring from damage. First use the j 45722 along with a specific long breaker-bar tool set to reverse-turn the fuel sender lock ring in a counterclockwise direction. Separate the Fuel Level Sensor and lock ring from the Fuel Tank by removing them one after another and discard the damaged fuel sender seal. Check the lock ring for any damage as well as warping and perform a ring replacement if needed. The next step involves installing the Fuel Level Sensor to the fuel sender module before cleaning the fuel sender sealing flange for new fuel sender seal installation within the Fuel Tank seal groove. Place the fuel sender lock ring and Fuel Level Sensor inside the Fuel Tank with the proper orientation so it will rotate in a clockwise direction. The technician should use j 45722 to install the fuel sender lock ring before reattaching both fuel pipes and the Fuel Level Sensor electrical connectors and finally reinstalling the Fuel Tank.
