Fuel Gauge Sender: Description and Operation
The fuel sender consists of a variable resistor, controlled by the action of an attached float in the fuel tank. The variable resistor consists of a screened
resistive material on a ceramic substrate, which produces a resistance value. Resistance should be 160 ohms (full tank) to 15 ohms (empty tank).
