Yeah, that's the right address, Ron.
Well, so far my luck in with the rusty gas tank has been all bad. First, the two biggest farm stores in town don't sell Phospheric acid because it's "too strong." Then the local auto parts store didn't have anything for rusty gas tanks and they didn't have the right size fuel line AND the only fuel filters they had were bigger than the carb. I'll try my luck with some motorcycle shops tomorrow, because it's after 5:00 and every place is closed. Anyone know where I could buy phospheric acid or Kreem online?
Oh, and I also tried flushing the loose stuff out by putting a little gas in the tank and shaking the bike around. The tank is part of the frame so it can't be removed and shaken. At least now the gas that comes out isn't brown and chunky!
