Leaking gas tank question

I have an internally coated tank that has been good for several years. But that is for internal rust and corrosion; I have some doubts how well that would seal up a leak.

For a temporary fix, if it is a pinhole in the tank, then try some of the tank sealer epoxy. Get the outside of the tank good and clean first; pretty easy to apply. But if three is one pinhole, there are likely more coming.....

BTW, pulling and installing these tanks is pretty darned easy....
