What tools are required to service and replace the fuel tank module on Buick Enclave?

The service process requires using a fuel sender lock ring wrench (J 45722) for tooling. Start with Fuel Tank removal and disconnect the fuel pump feed line quick connect fitting to the Fuel Tank module along with the evaporative emission (EVAP) canister front pipe quick connect fitting from the Fuel Tank. First redirect the tubed fittings and next unplug the electrical wiring connections for both the Fuel Tank pressure sensor and the Fuel Tank module. The j 45722 fuel sender lock ring wrench should be used to loosen the Fuel Tank module lock ring while avoiding any damage to the ring. Drive the lock ring off and lift the module with caution regarding the fuel level sensor float arm. You should tilt the module towards its side to unlock the tank opening before taking out both the Fuel Tank and the Fuel Tank module seal into an approved waste container. The sensor-fuel level measurement process should follow without interference unless the ring shows significant warpage exceeding 0.41 mm (0.016 in). In this case the replacement of the lock ring becomes necessary. To establish the setup put a fresh Fuel Tank module seal onto the Fuel Tank and then position the module at the right point before fastening the lock ring by means of the fuel sender lock ring wrench (J 45722). The next step includes attaching electrical connectors to the fuel sender wiring harness while placing both fuel pump fuel feed line and evap canister vent front pipe fittings correctly before you install the Fuel Tank module.
