Diagnostic & Repair Process

Understanding how the issue is diagnosed and the repair is performed can help you appreciate the labor involved and the potential for complications.

Suspected fuel level sending units are normally a very quick diagnosis. The servicing technician will immediately test the system and verify that the gauge is working properly when the proper conditions are applied to the circuit. If the gauge and all fuses are in working order, the voltage from the fuel sending unit will be compared to specifications, and electrical connections will be verified. The readings from the sensor will indicate if failure has occurred once the remainder of the system is verified in good working order.

The fuel level sending unit must be removed from the fuel tank. In most vehicles, there is a service access panel underneath the trunk lining or back seat; however, this is not always the case. Some vehicles require the fuel tank to be removed in order to access the fuel sending unit. Often, the sending unit and fuel pump must be replaced together. They are unbolted from the fuel tank, and disconnected from fuel and electrical connectors. Note, the technician will disconnect the battery prior to accessing the fuel pump. The new pump is inserted, connected, and tested prior to reassembly of the vehicle.

Prior to installing the fuel level sending unit into the fuel tank, we recommend comparing the movement of the old to the movement of the new fuel level sending unit. If one moves farther in either direction, the arm should be adjusted to ensure the proper level will display on the gauge.

Fuel contaminants play a large role in the health of an engine and fuel system. It is best to ensure you are adding fuel of the appropriate grade for your engine, according to the instructions in the owner's manual. When working with fuel, the battery should always be disconnected, and proper precautions taken against fire hazards.

Some fuel level sending units are difficult to replace, and some are simple. The level of difficulty will be described by the repair procedure for the particular vehicle, but most can be accomplished within an hour. If there is no service port for the fuel tank, the fuel tank must be removed. Fuel tanks are large, cumbersome, and can be extremely heavy. If the fuel tank must be replaced, a DIYer can handle the repair, but an assistant should be used to prevent injury or damage to the vehicle. The fuel tank combines electricity and fuel, and proper working knowledge of these components and safety procedures is a must. If you feel that you are unqualified for this task, leave it to a professional technician.

Replacing a fuel level sending unit, especially if it involves dropping the fuel tank, requires specialized tools such as:
