Just got my air pump set up yesterday, worked perfectly fine. For some reason today, i went outside and began pumping it up, and bled the hose to disconnect it, but this time its bleeding the gun and the hose at the same time? I can pump it to any PSI and it still does the same thing.

Gun is a Benjamin marauder pistol and pump is a venturi hill pump 5 with an adapter.

It's not the pump.. It's the one way valve in your Prod. It may have debris obstructing the one way valve or the sealing surface is cracked/damaged. Crosman customer service is top notch...just call them. Just be sure the air in the rifles's air chamber is actually rising as well as the pump to rule the pump out.
