The pressures that these tanks hold are minimal and i cant see why an air test wouldn't pick it up , unless i missread something and what your saying is the fuel corrodes the weak part of the weld over time, which would be a worry for everyone  |
It's all down to how good the tester is! I had a rad rebuilt by a leading rad specialist and it leaked. Phoned them up and the upstart on the phone said that it couldn't leak as it past its test. Took it back and the same guy tested it in front of me. He had 10 psi on it and I could see a small leak that he put down to air trapped on the core. I did no more than to wind his regulator up to 20 psi and the end tank exploded. The solder joint was dry.
Dax are in the hands of their suppliers. I'm sure they will do their very best to help. If a tank isn't available maybe someone on here will loan Toddy a tank for his SVA. The South East is not very local and my tank is one of the old steel ones 17 yrs old.
