regulator setup????

Go to your local proshop and bring your gun.  They can set you up with either marcoline (more flexable, wears down with co2 but lighter) or steel braided (less flexable, much much stronger) of the appropriate size, and any fittings you're gonna need to make your system work.  You could also just measure the distance and order either macroline or steel braided line on the internet.

Yeah it will be straight, as long as you have the correct length of gas line.

Yes you need the reg to drop the pressure of the tank into the range that the Comp air system can use.  In the future make your own thread... what you just did is called hijacking a thread.  And um... don't do it.

theres a hole in my Xchamber where u put the gas line, but its on the side, and my drop foward has the hole on the side, so the only way i could figure is to arch it, i was askin if there is somethin where the gas line could be straight acroos but the only way could be if somethin came out of the holes and went up then across like the pic shows, and i was askin if i could do that

I am not tring to be insulting but it sounds like you have never done a gas line before. You wil need the correct hose of the correct length, with the proper fittings and need to seal the line with the proper sealant. You may even need to realign the diff. parts to get what you want. Please take it to a shop. It will only cost you a few bucks more than the parts and you will be able to see exactly how to do it and ask questions,so next time you will be confident enough to do it yourself. I'm sorry but I'm a bit of a safety nut and blown line hurts bad.
