My Lister diesel generator instalation manuals say NO. Prob for the reason stated. I had to reject a big one on site once. Very unhappy supplier bunnies.

My diesel tank is galvanised. It's just over 35 years old and was condemned by a surveyor over 15 years ago. It's still fine and so is the engine BUT...
...I don't know that it is galvanised on the INSIDE. I'd have to take a great deal of boat to pieces to find out so I never have!
