Boosted Benjamin pump question

Does your pump leak air at the bottom coupling when you're boosting it?

Mine did until I found a gasket to put in there. Teflon tape worked for a bit, but the movement caused it to leak.

It seem's to have some weep holes at the base of the shaft that it's leaking from. Is that what was leaking on your's too? Cause I don't think tape would fix that but I'll try it later.

Didn't work. Anyone tried using jb weld on the weep holes? I've seen where people tuning the Hatsan rifles would plug some of the valve exhaust holes with jb weld, and you they said you could pick it out if wanted it out later on.

weep holes? mine doesn't have any that I saw. Mine was leaking where the largest nut secures it to the base.

Yes and it is no big deal. Just a little of the input air leaking off. Not to worry about cuz the compressor will make more.

Yes on that largest nut on the bottom their are 2 holes in slotted in it. I was wondering if you epoxied the whole bottom of it and sealed it off if that would work. In theory it should be able to chip right off, but I'm not going to be the first to test it lol.

Unless you want to take a small portable tank with you. I have a 1 gallon pancake compressor wired up to my truck and it will leak down faster than I can pump up.

[Sandspike]

well that is too much leak. Best stop it down but you may never get it completely stopped.

my hill pump leaks and i added 2x o-rings and a tight fit boss over top ;(-
my compressor is big tho so dont affect it

How much pressure are you feeding the hand pump? 5-6 wraps of thread sealant tape seals my Benji pump up just fine.
