Since you can hear hissing, how about using a length of hose as a
stethoscope? Just stick one end of a hunk of vacuum or fuel hose in
your ear, and probe with the other end. It's surprising
I might give that a try. I tried my mechanic's stethoscope, but couldn't
hear anything.

Well, I ended up pumping compressed air in there and didn't see anything,
but eventually found that the discharge port was leaking when I placed my
hand back there. As I said before, those are new o-rings and the bolt was
pretty damn tight, so I'm not sure how to make this thing seal correctly.
I'm still trying to figure out how to gain access to the stuff in the
cans,
but I think my can-tap will need to be permanently altered in order to
facilitate the process.
My tap had a hooked side that slipped over the ridge on the neck of
the can, and a cam lever that latched over the other
I guess I need a different can-tap. Mine looks sorta like this one:

I can see how that would be a problem. Does the metal bit come
out of the pliers? You could take a block of wood and scoop out
a trough for the fuel can, then drill a hole into which to

If I owned the shop, and I was set up for R12 reclaiming (I'd have to be

Sure! I just didn't have a hose clamp that large, and it was
quicker to flange one up out of wire than to go get one. Once
I had it, then I didn't need the hose clamp anymore, so I never
did go get one.

Hey Jim, thanks for the link. Are you still running the isobutane/propane
mix in your rigs? I was recently given an ancient Bear brand A/C recovery
unit (minus some key components), so now I have access to lots of spare R-12
hoses and fittings. I gather it would be unwise to operate the
