• Q: How to replace the Fuel Level Sensor in the fuel sender assembly on 2005 Cadillac DeVille?

  A: A proper procedure for replacing the Fuel Level Sensor starts by reducing fuel system pressure and completely draining the tank. First remove the Fuel Level Sensor access panel through a procedure of unbolting the access panel while also unlocking the rear compartment trim panel. Begin by disconnecting the Fuel Level Sensor quick-connect fittings while keeping shop towels on fuel pipe fittings for leak containment purposes and by releasing both Fuel Level Sensor and Fuel Tank pressure sensor electrical connectors. A Fuel Level Sensor lock nut wrench must be used to take off the retaining ring from the Fuel Level Sensor while keeping in mind the modular assembly module will rise after ring removal. Extract the Fuel Level Sensor while slightly tipping it to prevent float damage before you safely transfer leftover fuel into an authorized container. Before adding the new Fuel Level Sensor seal one must clean and check the Fuel Level Sensor sealing surfaces located on the Fuel Tank. Install the Fuel Level Sensor together with its lock ring using the Fuel Level Sensor lock nut wrench before reconnecting both speed connectors of the Fuel Level Sensor and Fuel Tank pressure sensor. The last steps include filling the tank with fuel before installing the Fuel Tank filler pipe cap while also reconnecting the negative Battery Cable. First turn on the ignition while keeping the engine off for two seconds before shutting it off for ten seconds then finally turning it on to watch for any gas leakage. The last step involves installing the Fuel Level Sensor access panel with bolts that should be tightened to 2 n.m (18 lb in). Then install the rear compartment trim panel and the fuel injector sight shield.
