My steel diesel tank has developed a small hole due to rust. I can't
take it out of the boat without removing the engine. Aside from this pin
hole the tanks looks in good shape. Have any of you used some sort of
coating on the inside of diesel tank to plug the leaking hole and
prevent further leaks?
Thanks for your recommendations.

There are sloshing compounds designed for this purpose.
I'm going to guess that the pin hole is at the lowest point in the tank,
where water has collected?
I'd be tempted to stop the hole with steel-filled epoxy or some such
(though getting the area clean and oil free would be a trick), then
place a drain tap in the tank.
In the past, people have expressed outrage at the idea of a tank drain,
but getting rid of water is getting rid of a life-threat in some
circumstances IMO ...
