I was going to patch my tank, it held 5 psi for 24 hours. I wire brushed it and one spot started to leak. If it was only pitted in one spot I would have taken a chance. But there were more places. So I bought a new 47 gallon aluminum tank.
Wow what a awesome tank. You can tell they know what they are doing. Sure I would have liked to have saved some money, but when you think of what could happen it's not worth it..
I had been using a portable fuel tank, always in the way, did not hold anywhere near as much fuel.
If you need a new tank for your SeaCraft , they have done a lot of them. They could build anything you need and it would be done right. Custom tanks any size. They are a first class operation, like the good old days. Also made in the good old USA. AWESOME.
