Fuel Gauge Half Scale

[uncleboo]

I installed a moeller gauge and sending unit set. Thought everything was fine until I ran out of gas with the needle stopping at just under a quarter of a tank. This style was adjustable so I readjusted it and now reading full scale. Not sure if this has anything to do with yours, but, worth mentioning. (had the float rod too long so it stopped at the bottom of the tank short of the position to read empty).
