Hello all! I purchased this a few months ago in pieces. It didn't include air lines and I need help on finding out what order they go? The smaller (piston) area is at the top of the pic, which ***** in on the left port, and out on the right. The larger piston is below the intake. But when I spin the flywheel, a larger amount if cfm comes out of the port on the right (the bottom of the two blue ones in the pic above) which leads me to think that that is the port which connects to the top of the air tank? However, on second thought, in that configuration that would mean that the two top ports (directly above the small piston) u-turn into each other? I'm not sure if that is correct? I'm just not putting it together? Can someone steer me? Thanks, Tom
