I've fixed some other things on my '56 Buick so now I'd like to see if I can get the gas gauge working. I filled the tank yesterday and the 19 gallon tank took 17.3 gallons so that's cutting it a little closer than I would like. I replaced the gasket for the sending unit earlier this year because it was leaking and the sending unit looked fairly new. When I turn on the ignition the gauge goes from below empty to E so I assume that means it's getting power. There's a ground wire from the tank to the frame so it should be grounded but when I removed the ground wire the gauge still went from below empty to E when I turned on the ignition. I was hoping there may be a simple solution to this problem without having to remove the tank again. Any suggestions? Thanks in advance....
