Well you don't mention year, but on my 69 BGT, the resistance from the
sender is 20 ohms full tank and 250 ohm empty. Just put a Fluke meter on the
sender (disconnect one wire going to meter for accuracy) and you can verify
the readings. That will tell you if the problem is the sender. Since the
sender could be getting stuck at either full up or full down positions, that
is my guess. Only takes a minute to test!!
