custom pro with cyclone feeder

im trying to install a cyclone feeder on my custom pro and it hasnt been going so great this project that everone I talked to said is easy has been a disaster but my question on the right side of the gun there is two holes thats were your supposed to hook the air line thinger up to the gun at from the cyclone feeder but it doesnt really specify which hole it needs to go in does this matter or does it have to be in a specific hole? right now both the holes just have screws in them so I didnt think it would matter but Im asking just to be sure

there isnt any holes that need to be punched out theres two holes were there are already screws and the instalation instructions just said to remove a screw on the right side that connects into the valve and put the banjo fitting in but both holes go to the valve so I dont know which place to put it.

Alright, there should be a new powertube that came with your cyclone kit. You need to replace your stock custom-pro power-tube with that one as it has the gas-flow siphon that the gas-thru bolt threads into. When finished, it should look like this:

Note the micro-line going down to the little tube that extends from the power-tube outside of the marker? There you go. Next time, read the installation instructions, they tells you all of this.

*sigh* the powertube on a custom pro, if it doesn't already have a cyclone or an RT on it, doesn't have the exhaust port drilled out on it. It's just a solid little piece of plastic to keep dirt and whatnot getting into the marker. HENCE, you need to change out the powertubes.
