I am interesting in testing my fuel sender and gauge for function and acuuracy while the tanks are out. I am using Auto Meter gauges. Please advise.

Hook them up as the instructions state. Extra car battery or a borrowed one works good. Battery chargers may not give you a good even power supply. Make sure you ground the base of the sender to complete the curcit.

Lower the float to a height that is the same as it sitting in an empty gas tank, gauge should read empty. Raise the gauge to a level the same as a full tank, gauge should read full.
