I know this is an old thread, I used the dirty side only J&L never collected more than moisture. I went to UPR, my neighbor here in FL works for them. I bought a dual valve and they shot a how to YT video. Not posted yet. I have pictures and UPR does sell an all parts configured hoses plug and play. Will report how much oil and contaminants it pulls out. The valve cover hose next to filler over to intake pipe is a direct fit.
I know there are those like me that need detailed installation instructions. They are making a dual can and single can config. PM me for details if anyone cares. I am over in SHOFORUMS mainly.
I am selling my J&L.
