I can dig out a pn tomorrow. Not too hard to find. I searched by npt size (either 1/4" or 3/8", most are 1/4" but I up sized my compressor and line to the tank to 3/8") filter seperator then you have to id one that has the auto drain that way you're not crawling under all the time. The water seperator is real important in high humidity areas if parked for long periods.
