Hi to all,

I'm currently converting my venerable gasoline boat to diesel and i thought
of reusing the fuel tank. However, a very clever person looking at my web
journal: www.langevin.biz/marinette34/repowering.htm pointed me about a
galvanized fitting on the fuel tank which linked me to think that the fuel
tank might be galvanized inside.

I opened the observation hole and looked at it with a flashlight, the
bottom looked like irregular patterns on the metal. Could it be
electroplated zinc ?

cheers

Andre,

Any way you look at it the tank is probably no good. Diesel fuel reacts
with zinc, and zinc is used in galvanizing. Sorry for the bad news.
