I bought a Shocker Sport Turbo a year or two ago, I hooked it up to air and it leaked. So I ordered new O rings and changed them all. Still leaked. Accidentally broke one of the wires connected to a solenoid. Finally got it fixed. I was hoping to just get a plain old ASA and throw that on the gun with some macroline but I came across a website talking about regulators for old school shockers. I'm assuming that I need a reg for my gun so that it won't leak...

My question is, do I need I actually need a regulator for my gun? The picture below shows what my gun looks like (mines a different color), the stuff I highlighted with the red box is not on my gun. If so, what kind and how much will it cost?
