haven't had a working fuel gauge since i bought my 53 truck. took the bed off and have easy access to the fuel tank. i decided to get a new sending unit and replaced it. hooked it up and still no change. i have a 12v system. i did install one of those additional equalizer thingamajigs directly to the gauge, and so far nothing.... Im ready to get my bed back on, but i want to finish this issue first.

Suggestions? thank you guys!
