Ford 7R3Z-9275-C Fuel Tank Sender Assembly

Relieve the system fuel pressure, then disconnect the cable from the negative battery terminal. Remove the rear seat cushion and take off the fuel level sensor access cover located on the right. Disconnect the fuel level sensor electrical connector. Using a hammer and a brass punch, loosen the fuel level sensor lock ring by turning it counterclockwise, and when it is loose enough, fully unscrew it. Before removing the fuel level sensor from the fuel tank, mark its relationship to the tank. Lift the fuel level sensor to access the quick-connect coupling for the crossover tube connected to the underside of the sensor assembly, and disconnect the crossover tube's quick-connect fitting by depressing the release button and pulling the fuel line out. After disconnecting the crossover tube, carefully lift the fuel level sensor out of the fuel tank, angling it as necessary to protect the float and float arm from damage. Remove and discard the old O-ring type seal, then clean the fuel sensor mounting flange and the tank mounting surface, ensuring to use a new O-ring type seal with a thin coat of heavy grease to hold it in place during installation. After installing the fuel sensor in the fuel tank, ensure the alignment arrows on the sensor mounting flange and the top of the fuel tank are aligned, and complete the installation by reversing the removal steps.

Disconnect the quick-connect coupling for the crossover tube connected to the underside of the fuel pump assembly by depressing the release button and pulling the fuel line out of the coupling.
