Gauge testing
Todd,
If you look at the illustration on the link I posted you see with a full tank of gas the resistance is very high thus a low amount of voltage is sent to the gauge and the lower the fuel gets, the lower the resistance gets, thus a higher level of voltage makes it to the gauge. So based on the illustration whith nothing connected the gauge should read full. If you wanted to test the gauge you could take 12 volts and a potentiometer and hook it up to the gauge and reproduce variable levels of voltage and see if the gauge responds accordingly.
