    Can anyone tell me why my fuel gage won't work, when the wire is removed from the tank the gage needle goes to full, when the wire is back on the tank the needle goes to empty.

    those senders in the old trucks last for a long time. the problem(that ive seen) is that the float on the senders /forums/images/graemlins/deal.gif are made of brass and after a while the brass will get a hole in it from wearing against the wire that holds it in and it will fill up with gas and will not float anny more, the way we fixed it on my buddys truck was to take it out and let it dry(of course ) and than we soldered up the hole, worked like a charm

    How many fuel gauges do you have? Do you read empty for both tanks?
