Problem with PMI 68 3000 tank

[acecl22]

Its a steel tank if that matters, every time I take it off of my gun, it leaks out of the pin valve. I have to jiggle the pin alittle bit to make it stop leaking, does anyone know what the problem could be, and how to fix it?

[acecl22]

come on guys/girls, someone has to know what the cause is

its a fill-nipple o-ring that seals it. they always go bad. more than half of the people i know who have them have that problem. if you still have waranty, send it to pmi. if not, you have to take it appart and replace the o-ring.

its not the fill nipple thats leaking though, its leaking around the pin, and only when i take it off of my gun

[joez]

i know that. i was telling you what type of o-ring was in there. it is a fill nipple o-ring that seals the pin valve. i can read.lol. it is a common pmi problem that is easilly fixable.

oh, sorry then, im not sure if I still have the warranty, ill go to my local shop and see if they have any of those o-rings, what size are they
