Perhaps I have the 'fuel gauge wiring concept' wrong in my head.

I would envision ground being at the gauge end of this circuit.

I picture the fuel gauge as being essentially a 'resistance meter'.

I would expect current to flow from the gauge, then through the sending unit, where the sending unit applies a certain amount of resistance (depending upon fuel level), then back to the gauge which measures this resistance, then to ground.

Am I on the wrong track?
