2008 Chevrolet Uplander Parts Questions & Experts Answers

• Q: How to service and repair the fuel pressure regulator and replace the fuel tank module on a short wheelbase on 2008 Chevrolet Uplander?

  A: A short wheelbase vehicle requires the fuel sender lock nut wrench (J 45722) as the necessary tool for Fuel Pressure Regulator service and Fuel Tank module replacement. The service begins with Fuel Tank removal and requires handling the fuel sender assembly by the fuel pipes to prevent joint damage. Remove electrical connectors from the module then clean all fuel pipe and hose connections to protect them from contaminants. Use proper equipment to disconnect the quick connect fittings that function for fuel feed pipe and evaporative emission (EVAP) pipe from the module. The fuel sender lock nut wrench (J 45722) should be used with a long breaker-bar to rotate the fuel sender lock ring counterclockwise for unlocking while preventing fuel from escaping into an approved container. First remove the Fuel Tank module and seal while keeping the discarded old seal and cleaning both sealing surfaces. Check the lock ring for both structural issues and deformation then get a new one if required. Put a new Fuel Tank module seal onto the Fuel Tank and then do the module installation while checking the lock ring orientation before applying the fuel sender lock nut wrench (J 45722) to tighten it clockwise. The technician must accomplish the final steps of reconnecting the evap pipe and fuel feed pipe quick connect fittings alongside the Fuel Tank harness electrical connectors and the reinstallation process of the Fuel Tank.
