Gas gauges on A-bodies

If you want a quick fix I run the equus Ford Chrysler gauge most accurate gauge ever! You can actually see it move up and down as the fuel moves around! $25

my Dodge Dart use to say I was on empty and I would still have 3 gallons in my tank, no more over filling at the gas stations Thanks to this gauge
Let me get this straight, You are saying this gauge will work properly with the aftermarket fuel sending units? I have a AutoMeter fuel gauge and that one will not work properly with the after market senders.
I appreciate the information
