Interesting, my fuel gauge worked fine on my touring for 2 or 3 years, but when I got it back from Carpenter after engine mods, it only went to 5/8 when filled. They denied they could have had anything to do with it, I've always assumed they bent the float rod changing the fuel pump, but then it worked once this summer, went to full once, then not again, after not working for 3 years, I'd be interested in your outcome, doesn't seem a bent rod could suddenly show full, even once.
