MasAyinde, those regs do not work in the reverse direction according to my research. Output is female and input is male. I ran into this problem using that reg when I built mine. Had to buy a male/male and female/female adapter to flip it 180. Just wanted to clear that up with you. I edited my post in your other thread as well. With this extra length it is a tight fit, and I would recommend removal of the airbox when using it to get proper clearance for the hose.

If it does in fact let air through in the reverse direction, the gauge reading will be input pressure from the compressor rather than output going into the intake. I opted to flip it 180 without testing to see if it will work as is, because I wanted to be able to see what psi was going into the car intake.
