Benjamin Discovery Leaks From Fill Probe

Just got a new Benjamin Discovery filled it up with a hand pump, released the air from the pump, then used the quick disconnect. To my surprise I heard air leaking and sure enough it was leaking out of the fill probe. Just got this gun, pretty disappointed about it. Please help I'd love to be able to fix it at home if possible. If you need more data than I would be happy to answer.

Jimmy, Let me try to help, if your fill adapter is leaking from the treaded end, you need two O rings Crosman part no 1761-005 = O ring AS568-016, if it is leaking from the nipple adapter, take the assy apart check the O ring on the end of the nipple adapter, Crosman does not show an O ring there but there is one. Carry it to your Ace Hardware store and find an O ring to fit. You also could call Crosman 1-800-724-7486 and ask for Part number 1761-101 that is the whole fill adapter assy.
 
Happy to say that my gun is fixed now I've solved all the problems so far... The leak was caused by the gun accidentally being cocked and another problem was air would drain from the gun when I blead the pump. Weirdly enough the reason why was because the pump wasn't fully compressed. Thanks for the help again I'm only posting this to help anyone with the same problem.
