I just completed my O.B.A. yesterday. I got a lot of info from the PBB but found very few pics. So I thought I would post my creation for those who would like to convert their stock Toyota A/C to O.B.A.

In the first pic the parts are (from right to left)- 1/2 male barb, 1/2 coupler, 1/2 to 1/4 reducer, 1/4 hex nipple, mini coalescing filter, 1/4 hex nipple, 1/4 check valve, 1/4 hex nipple, Furnas pressure switch (cut in 95 psi, cut out 125 psi) 135 psi pop valve ( under side), 90 degree elbow, 1/4 coupler.

FYI I got the OBA kit from www.frontrangeoffroadfab.com and it was only 160.00 and it bolted right on in about 10 minutes. you get everything you pictured and also get an air manifold with about 8 ports and it puts out enough air to run some air tools. mine saved my ass on upper heldo when my center pin broke and i needed my air cut off saw to modify a bolt.

With a 5 gallon tank I have been able to use all of my air tools effectively with my stock a/c pump.
Ditto, in fact, me thinks my impact (CH ) actually hits harder when I'm running it off my stock A/C OBA set up than it does off my garage compressor. Of course I do run the pressure a little higher on my OBA.

So with this kit for $160 you literally got everything needed? I've been toying with the idea of using my factory compressor for OBA. That would make it worth every penny in my book,being able to get EVERTHING in one kit.

I just can't get the thought out of my head of recharging the AC for the summer time.

Word of warning, I had a water/oil separator on mine just like that except with the metal bowl made by the same company. The air coming out of the compressor was so hot it melted insides. I have no idea if it will do the same to the poly bowl. These units are only rated for 250 degrees. Keep an eye on it. Nice work!!!!!
