Fuel Level Sensor
The fuel level sensor is attached to the fuel pump assembly and consists of a variable resistor controlled by the level of an attached float in the fuel tank. When the fuel level is low, resistance in the fuel level sensor is low and movement of the gauge indicator dial is minimal (EMPTY position). When the fuel level is high, the resistance in the fuel level sensor is high, and the gauge indicator dial movement is greater (FULL position).
When the fuel level drops to approximately 9.5 liters (2.5 gallons), the fuel level sensor supplies voltage to illuminate the low fuel indicator.
