Access to diesel fuel tank

I have a 1985 Hunter 28.5 that is leaking fuel when it is filled more than 3/4 full. My best guess for possible access without tearing through the bottom of the lazarette is to remove the centerline bulkhead from inside the quarter berth. Has anyone run into this before? I need to know if the bulkhead is correct or a waste of time ( I hope not) as I would rather not have to cut through the lazarette floor for access.

Well...

I believe that the fuel tank is built integral into the hull. I was told when I owned a 28.5 that the easiest fix is to cut out the floor of the lazarette and drop in a manufactured tank, but thankfully, I never had to do it. Hopefully, someone out there has done this already and can provide more info. Peggie can steer you to a tank manufacturer.

Intergral tank

Unfortunately the tank is moulded in the boat. Pretty messy job and I think that there is some decription in the archive. If you don't need the room in the lazerette, I would consider just placing a free standing tank on top of the original tank. I think the original tank was 11 gallons so it wouldn't be that instrusive. If you do rip it out let the board know. Good luck.

But why is it leaking?

That seems like such a peculiar leak that perhaps it's mendable from the outside of the tank with some kind of glue.

I WOULD CALL HUNTER BEFORE....

you start cutting, Chuck. On my 1989 H28 the 18 gallon tank was strapped to the hull. Access for replacement appeared to be through the aft bulkhead. Hunter can tell you for sure. Good luck. Terry

Should be repairable

Chuck: Based on these replys I would think that this is a repairable problem. It should be a fiberglass tank if it is molded into the hull. One option would be to apply a fiberglass patch over the break. You may need to get some expert opinion on patching something like this if there is diesel in the crack. The other option is to cut the top out of the existing tank and insert another inside it. I have no idea what you are dealing with in regard to space or accessibility, so this is just an idea.

Thanks

Thanks for all the advice and suggestions. I am planning on removing the small plate which has the supply and return lines and fuel gauge sticking through it today or tomorrow. This is on top of the tank (lazarette floor) and I am hoping after pumping out the tank I can see or feel enough to figure out how big the hole is and where. It is virtually impossible to see or access the outer sides of the tank to be able to patch it externally. If I can't get to it I plan on installing a new tank either inside the old one or in the aft end of the lazarette. If I am able to install one inside the old one I am going to do what I think should have been done originally, close the opening with an access plate instead of a solid deck.
