Hunter '37, 1980 Cherubini The 42 gallon diesel fuel tank has just sprung a leak. I'm guessing I'm loosing about a gallon a day to the bilge. I'll, of course, clean up the bilge, but what's the best approch to the fuel tank? It's glassed in under the rear berth, form fitted and no way to remove it without putting huge holes in my boat. Please talk to me. I just spent a couple thousand dollars getting the power train fixed and my pockets all that deep. HELP!!!
