The voltage to drive it is really small. It needs 15 millivolts for a max scale reading & 65 millivolts for a minimum scale reading.

Ian,
Was that determined with the adjustable voltage source with 68 Ohm series resistor? Was this measured with a DMM? Be curious if this is pulsed like the fuel gauge was. You could probably get a much larger voltage swing using a larger value series resistor. First need to know if those voltages are based on DC state or average of pulses.
