Fuel Sender Assembly
The fuel sender assembly is located in the fuel tank. The fuel sender assembly contains the electric fuel pump, the fuel level sensor, the fuel pressure regulator, and the fuel filter. Most of the fuel sender assembly components can be serviced separately.

The fuel level sensor is part of the fuel sender assembly. The fuel level sensor (1) consists of a float (2), a float arm, and a variable resistor (1). The fuel level is measured by the position of the float in the fuel tank, and is indicated by a gauge in the instrument panel cluster (IPC) assembly. When the fuel level changes, the float position changes. The change in the float position increases or decreases the resistance reading of the variable resistor. The change in the resistance causes the position of the fuel gauge pointer to change.
