Gun tank refill bleed

[JKaplanwit]

I had to empty the gun air cylinder but now I can't get it to refill. It just bleeds out the through the barrel.

Suggestions? Thanks

Try cocking the gun

Are you by chance hand pumping? If you are there is a chance the pump isn't producing enough pressure fast enough to initially seal the tank to build the pressure. I know some guns can only be refilled from a tank or compressor when fully empty. If you aren't hand pumping disregard this.

I tried cocking the gun. No change.

I'm filling from a scuba tank. 

Thanks.
