2000 Cadillac Seville Fuel Level Sensor Parts and Q&A

• Q: How to replace the Fuel Level Sensor assembly on 2000 Cadillac Seville?

  A: Almost every replacement process depends on two essential tools - fuel pressure gauge (J 34730-1A) and Fuel Level Sensor lock nut wrench (J 39765). The first step requires both fuel system pressure relief and enough fuel tank draining to reach 3/4 of the tank to avoid fuel leakage. First remove the spare tire cover and jack and spare tire before extracting the rear compartment floor trim to gain safe access to the metal components. Proceed by taking out the Fuel Level Sensor access panel bolts then disconnect the quick-connect fittings from the Fuel Level Sensor while separating electrical connectors from both the modular Fuel Level Sensor and the fuel tank pressure sensor. Tip the modular Fuel Level Sensor while removing it to protect the float operation and transfer remaining fuel to an authorized container. Remove the Fuel Level Sensor retaining ring by using Fuel Level Sensor lock nut wrench (J 39765) which will enable the modular Fuel Level Sensor to rise. Check and clean both o-ring sealing surfaces and position the new o-ring onto the fuel tank before confirming that the Fuel Pump Strainer remains straight and not obstructing the float arm movement. Install the Fuel Level Sensor and the retainer cam with the help of a Fuel Level Sensor lock nut wrench device (J 39765) before reconnecting quick-connect fittings along with electrical connectors to the fuel system. To verify the absence of leaks, follow the specified procedure of turning the ignition on and off while monitoring the battery connection state. Attach the Fuel Level Sensor access panel and fasten its bolts to 2 n.m (18 lb in) before installing the rear compartment floor trim. The last step involves installing the spare tire followed by the jack and spare tire cover then refueling the tank while installing its filler pipe cap. Finally, secure the rear seat cushion and intake manifold sight shield with 3 n.m (27 lb in) torque values.
