Can someone give me some advice on my gun? I have a 98 Custom ACT which has been leaking air. The last time I used it I put a hopper through it just fine, I then left the tank on and went and ate dinner. I came out of the house a half hour later and the gun wouldn't shoot. I switched o-rings on the tank, that isn't a problem.
When I screw my tank in the CO2 starts coming through the gun (even if I don't pull the trigger) and comes out by the bolt. It empties the tank and want let me shoot a paintball. Can someone give me some advice. My local PB shop just went out of business, so I am kinda stuck.

Thanks

Try cocking the marker prior to air it up.

Sounds like your valve is stuck open. Disassemble the marker and check to force it takes to push in the valve pin. Could be a seal inside has gone bad. How old is the marker? Did you buy it new or used? Are there any mods to the internals?
