• Q: How to replace the Fuel Level Sensor assembly on 2005 Chevrolet Impala?

  A: The first required step for replacing the Fuel Level Sensor assembly becomes the relief of fuel system pressure. Establish adequate ventilation during replacement to decrease fire risks while cleaning the locations where fuel pipe and hose connections are mounted to avoid fuel contamination. Before starting drain the tank fuel then lift and supporting the vehicle. You should loosen the fuel fuel hose clamp prior to removing the Fuel Tank filler hose. You need to remove the fuel feed and return pipes at the Fuel Filter area together with the evaporative emission (EVAP) pipe from the front of the Fuel Tank. Lower the exhaust system by removing rubber hangers and separate the evap fresh air hose at its splice point while removing Fuel Tank shield push pins and corresponding shield components. A transmission jack will provide support to the Fuel Tank before you disconnect the Fuel Tank strap bolts. Lift the Fuel Tank out of the vehicle while wearing appropriate safety equipment before establishing it in an appropriate work location. The next step involves disconnecting Fuel Tank pressure sensor and Fuel Level Sensor electrical connectors before cleaning all fuel pipes and the level sensor assembly while disconnecting quick-connect fittings from the Fuel Level Sensor assembly. You must remove the Fuel Level Sensor retaining ring followed by the modular Fuel Level Sensor assembly before cleaning and checking every o-ring sealing section. Install the new o-ring on the Fuel Tank while maintaining the Fuel Pump Strainer in its proper design without twisting or folding it during assembly. Replace the new Fuel Level Sensor assembly after you secure it using the retaining ring and then connect the electrical connectors followed by the quick-connect fittings. Tighten the Fuel Tank strap bolts to 47 n.m (35 lb ft) after you reset the Fuel Tank with the transmission jack. Replace the Fuel Tank shield along with push pins as you reconnect quick-connect fittings to both the Fuel Filter area and the evap pipe near the front of the Fuel Tank. The evap fresh air hose should be reconnected first followed by mounting the Fuel Tank filler hose while verifying that the clamp correctly positions itself on the tank port. Secure the Fuel Tank filler pipe hose clamp at 2.5 n.m (22 lb in) and then rehang the exhaust pipes before lowering the car for fuel addition and installation of the fuel filler pipe cap. The procedure for checking fuel leaks involves setting the ignition to on for 2 seconds before turning it off for 10 seconds and then repeating the on cycle while examining for leaks.
