My fuel gauge isn't working properly. Could be the ground, but where should I find it? I found a grounding wire screwed to the car's underbelly at the front passenger side corner of the tank. This is probably it. Should it be? There doesn't seem to be anyway to service it without dropping the tank. My TAN wire is properly routed.

I was thinking that if I'm doing the tank, it's good measure to replace the sender on the old girl. Agree?
