  Q: What tools are required to service and repair the fuel tank pressure sensor and replace the fuel tank module for long wheelbase on Chevrolet Uplander?

  A: The necessary tool for servicing and repairing the Fuel Tank pressure sensor with long wheelbase module replacement becomes the fuel sender lock nut wrench (J 45722). Reposition the Fuel Tank in the first step then keep off fuel sender assembly contact with fuel pipes because this generates joint damage. When servicing or repairing the Fuel Tank pressure sensor disconnect the electrical connectors from the Fuel Tank module then clean all fuel pipe and hose connections to stop contaminations. Begin by detaching the quick connection ends serving the fuel feed pipe and the evap pipe from the module. Tighten the fuel sender lock ring by using the fuel sender lock nut wrench (J 45722) with a long breaker-bar through counterclockwise rotation to drain the fuel properly into an approved container. Extract the module together with its seal unit from the Fuel Tank while discarding the outdated module seal and cleaning the attachment areas. Check the lock ring for damage along with warpage then replace it when needed. Pay attention to the Fuel Pump Strainer during new Fuel Tank module seal installation because twisting or folding must be avoided. Use the j 45722 fuel sender lock nut wrench to break the lock ring clockwise into the Fuel Tank until it reaches the correct position. Reinstallation of the Fuel Tank must include evap quick connect fittings and the fuel feed pipe quick connect fitting to the module and the connection of the Fuel Tank harness electrical connectors.
