I took the rear cap of the compressor and had it tapped at the machine shop.
1/4" pipe thread on the discharge, 3/8" pipe thread on the suck side.
I ordered an Viair leader hose and an ASCO water seperator from Ricky at whynotfab.com and hooked them up to the discharge side.
The fittings I got from the local Parker store and used it to hook the in-line oiler i got from sears and the filter from autozone.
I also ordered an ASCO pressure switch from Ricky. You hook it up like any othe 12v compressor.
hope this helps, I don't have it in the truck yet, but i hope I should this week.Email me with any questons you might have.
