My .457 Texan with the CF Bottle and TX2 Valve is leaking. It is leaking from I guess its called the Top Hat. I try to fill and the air escapes thru the valve. I have tried opening the breech and leaving it open, pulling the valve as far forward as it will go, leaving the breech open, but still seems to be letting all the air go straight through. Any suggestions? I would greatly appreciate any. Thanx.
