air leak from asa?

[zynniv]

i just got a used impulse with a max-flow regulator, and when i screw a co2 tank in it shoots air (massive leak) right back out from where i screw it in. ive tried adjusting the pressure, but the gun just pressurizes up to the pressure and then shoots the air out of the asa. anyone know whats wrong?

(i have changed the tank o-ring)

does your impulse have a vertical or manifold (horizontal) reg?

[zynniv]

sorry, it has a max flo horizontal reg...
i believe its a bottomline, the asa is directly attached to the asa, and then the hose goes from the reg to the foregrip

I thought so.
most horizontal maxflows have this problem. The pin in the ASA is too long, you'll have to put an o-ring in the ASA, and screw the tank down on that, and/or file down the pin inside the ASA (a dremel is great for this)
