So I would ground out the tan wire as close to the tank as possible and if the guage goes to full it is your sending unit or a connection right at it, etc. If nothing changes, then you have wire problems farther up the line closer to the guage or the guage itself. I had a similar problem and after trouble shooting I found it was the guage. Changed it and everything worked fine. Hope this helps.

I hate to admit it, but he is pretty good at electrical stuff, not great or anything by any means but good. I'd take his advice if I needed it but I never need help so that's not a problem.
