fuel tank questions

[billythekid]

my tank was only 3 years old and I brought it back to get tested and epoxy coated. They tested it held 5 psi BUT, the pitting was more than half way when they measured it. Legaly he said they couldnt paint it and they needed me to sign off on it. He said the tank look like it was 15 years old. The 500 bucks for a new tank wasnt worth putting the boat back together with a questionable tank. It is very tricky for them to weld on a tank that had gas in it. The has to be flushed a bunch of times and then they pressurize it with argon to keep it from exploding.
