Steve, good chance its a ground along the way that finally disconnected or rusted out of contact. You can ground brown wire that goes to your sender at the tank and see if that pegs the needle full, then you know the guage works.
Then also check the grounds at the tank and the console ground. Also try a search in here, there have been many little things that cause guages to act up, you might find one similar to your issue.
Im no elec. genious by any sorts but of all the reading Ive done in here on elec. problems most of them have eneded up being ground related.
