The hose that came with the stuff i bought is 1/2", I think I'm gonna have to go buy some 3/8" so it will be easier to run throughout the jeep

I just found this write-up. Awesome awesome. I was thinking....I have an old electric compressor in my shed. The motor took a dump. If I use this it will give me most of the parts I need. A few fittings, some hose(also have an old one) an oilier, and a dryer and I'm all set.

I haven't read the whole thread yet so someone may have suggested this already:

You can keep the condensor as part of the the OBA system, just take the output line from the condensor as your starting point instead of tapping the air right off the back of the compressor. The condensor will cool the hot compressed air coming out of the compressor, then you can put your water separator in line right after the condensor. The most of the water in the air will condense as the compressed air cools and get trapped before it makes it to your air tank. You'll still have to check and drain the tank once in a while but not nearly as often.

I've considered this but for simplicity i avoided it, condensers just seem to be really prone to leaks.. Good idea none the less.

Hmm. I've never had a condensor leak in an AC. But its probably more likely once you convert it to air because the moisture can corrode it from the inside.

Speaking of leaks... how about adding a check valve all the way back at the tank in the supply line in addition to the one at the compressor. That way if you get a leak between the compressor and the tank, it won't drain the pressure out of the tank. Come to think of it you probably don't need a check valve at the compressor at all since compressors have a check valve on the outlet of each cylinder inside them.

You don't just get oil in there with the seperator. You get water also. It is called an oil/water seperator. Plus I don't know how you would pipe it since the drain on the bottom isn't a standard thread. At least on most seperators.

I copied your idea and here is what I came up with. I made the front output so it can stick down and be sheltered in the fender area. Rear conmes right off the tank. Total cost was about $140 but I bought from a local hardware store so prices were higher.





My tank I used an old firefighter oxygen tank
