FUEL GAUGE AND SENDING UNIT CIRCUIT
The fuel gauge and sending unit circuit consists of the fuel gauge/hour meter, fuel level sending unit, key
switch and connecting wires. The fuel gauge sending unit picks up power from the key switch when the key
switch is turned to the ON position. The power goes through the gauge to the sending unit at the fuel tank. The
sending unit tells the gauge how much fuel is in the tank (Figure 11-12, Page 11-12).
