Great problem solving and write up! I was wandering around the shop a few nights ago scoping and scrounging parts off a few engines for that exact same project. On several occasions I've been pelted by broken or jammed airlines that were snapping at my @ss like Indiana Jones so I believe the one main difference in my system is that all of my onboard 'plumbing' will be hardline tucked into the framerail. I'd be mortified if a line popped, ripped an interior panel loose and beat the hell out of my passenger(s)

Excellent idea, do you have any write up info or photos for us?

A little off topic, i searched the net, and didn't have fantastic results.

I'm putting a TBI 350 into my jeep, and wondering if the stock AC pump on Chevy works in the similar manner as the jeep (aka, using the tool oiler...etc)

I was wondwering what I was going to use that useless a/c compressor for! I copied your parts list, but where did you get your parts from? While my girl is down I want to do this mod while waiting on UPS to deliver my other parts!

it depends, if its a roatary then yes, if its a piston compressor then it should hold oil in the crankcase.

The tank i got on ebay but can be bought on quadrtec, the manifold came from www.northerntool.com, and pressure switch was from quadratec. Everything else was bought at a hardware store.

awesome thread. lots of great ideas. like everyone else, too bad i have good AC.

i'm gonna be cutting out my rockers and welding in some big square tubing, think i'm gonna tie the tubes together and make them my tanks, somehow. they won't be compressed for a long time, but someday.

any thoughts on putting in a valve that you could put on a switch that could go between running AC and compressing air?

It is possible but not very cost effective. Once you open the system, you will lose the freon and then you won't have AC. You could possibly T-off both lines at the compressor with a valve on each of the 4 lines. Then open the AC valves when you want AC and the air valves when you want air. But each time you do that, you will lose some freon that is trapped between the AC line and the compressor. Use the air enough times, you will lose all the freon. You would have to buy some AC manifold gauges to check the pressure in the system and to tell if you need to recharge your AC system.

You would also need to get valves that don't have any plastic in them since the plastic may not be compatible with r134-a freon. The freon might eat the plastic then you will have leaks.

Sorry must have missed this.. But its been holding up great and i use it once a week atleast. Especially with the wet conditions with the snow/melting snow. Everyone im with, normally a group of about 4, airs down and then i air them back up. My only issue has been the fact that on really cold days, like in the 20's, a couple of the exterior fittings leak a little bit, but on warm days no issue.

Air management for conversion to OBA

Thanks Russo for this great write up. I'm starting my conversion next weekend. I found a website that provides parts and air management materials at a reasonable price. Actually, very reasonable. I've already ordered my tank, pressure switch and gauges from there. They specialize in air suspension setups, but the parts can still be used for OBA setups. check it out.
