When fueling up the other day we had an overflow at the fill and at the vent on the stern. (Way more poerful pump than I was used to). Not that much fuel spilled, but now there is some diesel dripping from the forward area of the tank and i’m not sure if its from a leak or the overfill event.
I’ve crawled all over the lazarettes and the tank and all the fittings look fine and there’s no fuel on the top or sides of the tank.
Do I have a leak or is there some other place the fuel could have squeezed out when we overfilled? Right now I’m hoping it just a clean up problem… 🙁
Thanks,

Patrick,
Many of the aluminum tanks supplied by Pearson developed pinhole leaks.
Hopefully this is not the case with your tank, but the hydrostatic pressure
of the fuel overflow might have been enough to open a pinhole. I believe
the pinholes were caused by electrolysis between the tank and the hold-down
straps. Earlier 424s came with iron tanks, which did not have this problem.
If there is no fuel evident on the tops and sides of the tank, could the
fuel you see have been there before and you only noticed it because of the
spill?
Clean it up and see if any fuel comes back. Good luck.Regards,
John Stevenson

Gave everything a good cleaning laid down fresh oil cloths and we have a
drip, but its a very light drip (couple of drops today). I think we’re going
to leav it alone and get to San Francisco as there doesn’t seem to be any
options to fix it here in Newport, OR.-p

Lee,
No, I don’t know when Pearson changed the tanks to aluminum. My new tank is
aluminum, but the hold-down straps are isolated from the tank by cork
strips.Regards,

Going to have a guy come downa nd take a look today… just talking on the phone he had an interesting suggestion of removing the fuel, and the old tank, throwing in an interim solution (bladder smaller pre-made tank) to get us down the coast while we waited for a new tank.
Hate having to deal with this in a hurried manner… and its a holiday weekend too… yay!

Don,
I can only guess at this, but reasons not to use bladder tanks1. Difficult to secure in boat
2. Limited capacity compared to metal tank
3. Coast Guard approved for fuel?
4. Insurable?
5. Difficult to attach fittings
6. Short useful life compared to metal tankRegards,
John Stevenson

Flexible tanks come in all shapes and sizes. See link here to a flexible tank company that advertises in Professional Boatbuilder:
http://www.atlinc.com/
I’ve heard of some people who simply cut the top off the old tank then installed a flexible tank inside. Don’t know what a custom sized flexible tank would cost, probably plenty. This arrangement would probably address many of John’s concerns and would have the additional advantage of no air vent.
We have an aluminum tant which I repaired by encapsulating it in fiberglass and West epoxy. About 8 years since and no leaks, kow!
