I agree with the concerns about using JBWELD in the fuel tank but on their website:
http://jbweld.net/products/uses.php they state plain old JBWELD can be used in fuel tanks. And I agree about being overly cautious with fuel tank leak issues. I just brought it to my house and it's in my driveway and my dad put 4 or 5 gallons in it so as a first test I will fire it up in the driveway and let it run for awhile and observe from a distance.
But we took it out before when we had the leak and didn't know it and it was acting like it got air in the system. We couldn't get a vacuum(?) on the system upon switching to a portable gas tank onboard. I do intend to switch out the tank if I keep the boat just want to make sure the boat is seaworthy and I won't have to immediately repower it.
I guess what I should probably do is empty the internal repaired tank and switch to the external 6 gallon portable tank I have and maybe carry another on board gas can with another 6 gallons (I know there are safety issues doing this) to test it out for the summer when I use it. Unless this is a cardninal sin, you folks tell me if it is.
Thanks for the comments and please keep them coming.
