Highlights- Measures and indicates the amount of fuel in the tank.
- Float moves with fuel level, altering resistor's resistance and signal to the dashboard gauge.
OverviewThe fuel gauge assembly typically consists of a float, a metal rod, and a variable resistor. The float sits on the surface of the fuel and moves up and down with the fuel level. This movement is transferred via the rod to the variable resistor, which changes its resistance based on the position of the float. The variable resistor is connected to the vehicle's electrical system and sends a corresponding electrical signal to the fuel gauge on the dashboard, indicating the current fuel level.
