Q: How to Safely Service and Repair a Fuel Level Sensor on Lincoln Mark LT?
A: The first step for fuel level sensor maintenance requires removal of the fuel pump module under smoke-free conditions because of the explosion hazard posed by combustible vapor mixtures. Note down how the fuel level sensor wire routes itself because this information will help install it correctly. The service procedure starts with removing the heat shrink tube from the electrical connector and then detaching the connector. Next step is to separate the fuel level sensor wire from the fuel pump module wire harness. Pull out the screw then raise the fuel level sensor from its place. When installing the sensor position its wire in the middle of the fuel pump module. To install the fuel level sensor in gasoline vehicles both wires should pass to the rear of the sensor plate so the grounding eyelet stays on the sensor front side. Attach the sensor to the fuel pump module then apply the screw through the grounding eyelet before tightening the screw. Flexible fuel vehicles require both fuel level sensor wires to be routed behind the sensor and along the left side with the grounding eyelet placed on the front side. Secure the sensor onto the fuel pump module while using the screw to fasten it before placing the wire inside the module. The wire harness requires the heat shrink tube to slide over it before connecting the electrical connector through heat gun application instead of open flame usage. The fuel level sensor wire needs to wrap around the fuel pump module wire harness to avoid interfering with the fuel gauge sending unit float arm and the fuel pump module and fuel tank must be restored in their proper positions.
Q: How to Safely Service the Fuel Level Sensor on Lincoln MKX?
A: Service of the fuel level sensor requires following basic safety precautions to protect against hazardous mixtures and to exclude smoking tobacco and open flames together with personal electronic devices. The service of the fuel level sensor starts with removing the fuel pump (FP) module while also cutting the power connector from the fuel level sensor. Start by depressing the lock tab and push the fuel level sensor towards the top until it exits. Start the installation by following the inverse steps used for removal to finalize the process.
Q: How to Service and Repair a Fuel Level Sensor in a Fuel Pump Module on Lincoln Town Car?
A: The service of the fuel level sensor requires technicians to start with fuel tank removal. Disconnect the electrical connector for the pressure transducer which resides at the top rear side of the fuel tank and remove the two harness retainers from the tank. Handle the fuel pump with caution while cleaning around its mounting flange because any roughness may damage both the float arm and filter. Carefully remove the fuel pump by unfastening its six bolts and tighten the bolts to 10 Nm (89 lb-in) before installation. The old fuel pump mounting gasket deserves disposal before checking the contact areas between the fuel pump module flange and fuel tank seal. A new fuel pump module or fuel tank needs to be installed whenever the seal contact area shows bent or scratched or corroded condition. Recovery of the fuel pump installation requires performing procedures in the opposite order of removal.
