Don't know if it is the right way or not just what I felt would make the motor guard filter element  last longer by pre separating some of the moisture out. The pressure regulator coming out of the Sharp separator was really not needed as the 45 machine has a built in regulator. I just got a good deal on the Sharpe unit with it and decided to utilize it.

I don't advise anybody to do the same as I do :-) see disclaimer below.
