    Q:
    How to replace the fuel tank module (NT7) on Buick Lucerne? Posted by Customer
    A:
    Before replacing the Fuel Tank module (NT7) personnel must first follow the correct method to reduce fuel system pressure. First unfasten the rear compartment liner and fuel sender access hole cover bolts before removing the cover itself. The sender requires removal of its fuel feed rear pipe quick connect fitting after which the pressure sensor and sender get their Fuel Level Sensor wiring harness electrical connectors (1, 2) taken off. The j 45722 (Fuel Sender Lock Ring Wrench) should be used to remove the fuel sender lock ring by turning it counterclockwise while keeping the lock ring from getting damaged. Use the j 45722 to unlock and remove both the lock ring and the fuel sender assembly but ensure the Fuel Level Sensor float arm remains straight since tilting prevents bends and drain the fuel from the reservoir bucket into an approved storage container. We should remove the old fuel pump module o-ring seal for inspection while testing the lock ring for any damage that extends more than 0.41 mm (0.016 in) requires it must be replaced. Install the new fuel pump module o-ring seal onto the Fuel Tank then fit the float arm of the fuel sender while tilting the assembly before lowering it into position inside the tank. Secure the module lock ring clockwise using the j 45722 until it reaches full lock position. Reattach the Fuel Level Sensor wiring harness electrical connectors (1, 2) as well as the fuel feed rear pipe quick connect fitting. Use the correct instructions to turn the ignition on and off while verifying that no leaks exist when checking for leaks after attaching the negative Battery Cable. Conclude the process by installing the fuel sender access hole cover which needs to be bolted to 2 nm (18 lb in). Proceed by reinstalling the rear compartment liner and intake manifold cover.
