Ok, I have an autococker 2000, Drop Zone III and an Air America Raptor 68ci 4500psi nitrogen tank. I bought the macroline kit at paintballgear.com seen here:http://www.paintballgear.net/macrohosekit1.html
The silver connecters have threads on one side and the spot where you put the macroline on the other. I used one of them to screw into my stock regulator. So I have the macroline connected to my gun, but i don't know how to connect it to my nitro tank. The Raptor nitro tank has 2 airports on the side, one says "out" and one says "in". It is seen here:http://store6.yimg.com/I/actionvillage_1625_30793016
Then there is the gauge in between them. What sort of connector do i need to connect the macroline to one of those airports?
