Subject: TWL: Keith's peel job and tanks

I saw the pics of your peel job in progress. Wow. That makes steel hull care
not seem so daunting now!
(snip) from Keith
....We drilled a few holes in the bottom of the keel to let the water drain
out, got maybe a gallon or so out and it stopped dripping for a couple of
days. Guess what? It started dripping
(or maybe weeping would be a better term) DIESEL......There are no visible
leaks anywhere inside the boat. I'm really HOPING that this is diesel that
somehow got down into the keel over the years, and the weeping will stop.
Anyone else who wants to cross their fingers with me is welcome.

I'll cross my fingers with you but I have this theory about large
projects--everything . . . absolutely everything . . . is connected
together. I very carefully and scientifically developed this theory after I
went to replace the dishwasher in my house, and ended up replacing the sink,
disposal, under-sink plumbing (all of it), counter-tops, stove, all the
drawer hardware, and two light fixtures. The day I thought I was finished
the top glass FELL--just fell--out of a large front window in another room.
Yep it is all connected together. When you fix your tank (sigh) you will
have a engine coolant problem, then your anchor will break in two . . . or
something like that. The order and severity may vary.
This is not getting to me on my boat, 'cause the entire thing is apart
anyway! I figure the day I finish the boat, the car will break in half, the
cat will turn into a dog, etc.
(snip)
I thought about pressurizing the tank a bit through the vent line and see if
we get leakoff. At least I might be able to isolate one tank if it's a
problem. Any other ideas/experiences would be appreciated.
(endsnip)
A bit of a warning here . . . no more than 3psi pressure in this kind of
testing. That's "three" psi. 1 or 2 psi even better. There is lots 'o
surface area in tanks. A little pressure makes HUGE loads. You need a
sensitive air pressure guage to do this (low pressure scale). Not expensive.
Recheck all your fittings too . . . it really is not very visable if they
are not leaking much, and that cup or two could have leaked over
days/weeks/etc. Diesel leaks can travel a long way too. Dry and clean the
fittings thoroughly, then sprinkle them and the surrounding areas with baby
powder (talc). Any leak/seepage will become visible reasonably soon. Don't
rule out a leak in a vent line, or in a fill line/fitting that only leaks
when you are fueling.
Good luck, keep us posted.
CUAgain,
Daniel Meyer
