Big Red Air Valve Questions

[jugernot]

I have split my big red valve into two parts. So now I have two set of two valves. I have put the set on each side of the frame.

I wanted to connect the valves with a supply line going from "suppy" of one to the "suppy" of the other. I also wanted to run a suppy line from one tank to the other tank.

Will this cause any problems?

Another question, There is an exhaust port on the valve system. What do i need to connect to this? Nothing is shown on the instructions.
