My 20+yr aluminum diesel tank developed a slow leak this past season. I get a small amount of fuel
in the bilge after a week or so on the mooring, especially after I top off the tank. I thought I should repair
I though I might access the tank through the sending unit opening, drain the fuel
, clean the insides, and find the hole or crack to seal from within. The problem is, the opening at the top is so small, I can't really see much inside. To make things more difficult, the fuel
tank is completely glassed-in under the port lazarette, so there's no other access.
So here's the question: do I cut out old tank out and replace it (a big messy job), or can I just leave it there (empty, of course) and buy a Moeller-type tank to install above the old one. I have room above the old tank, inside the lazarette next to the holding tank
. Is there any problem leaving the old tank where it is? I'd rather not cut any fiberglass if I dont have to.
