Ok, so its go with the OBA set up with the factory a/c compresor.
Its just going to cost more than I thought, I was at home Depot today pricing needed parts.
i should have it done by spring time.
I removed the factory jack today to make space for the oba and re attatched the stock hoses, the intake hose can be reused by cutting off one end and adding an oiler and a filter
The output stock line can also be reused as I have read here that the hose gets hot so factory would be the way to go, it already has the correct fittings to the pump.
Im trying to go low budget as possible

not sure if it's the same as yours but i used 3/4" npt fittings to thread directly to my a/c compressor.... i didn't use stock lines. and the black iron at home depot is much cheaper than solid brass

no tank.It looks good for reairing tires.What do you think?

those capped ports arent ports, they are the fill and bleed taps of the threaded lines, the black capped one is used to fill the AC system with freon, an the red capped is the high pressure "service" port, some AC system dont have those fittings on the hoses as others do, i.e... my 92 YJ has them on the lines and not on the compressor, but a friends OOOOOOOOLD CJ has it in the compressor just like the one you have pictured, as far as specs on that compressor... cant help you there

hope this helps

That is a Sandem compressor. You only use the ports that are uncapped in the first picture.

i used two 5 gal tanks mounted on the fenders in the rear. i did this so that if i had to, i could turn the jeep off and still have pressure. any tank will work, thats the bottom line, if you can hold air in it and it has a place to mount a manifold, it will work. worry about where you will mount it and that will be the foundation of your decision. it is nice that this tank has a pressure switch on it. again anything will work.

I personally wouldn't go any smaller than 1/4 " on all lines, fittings and ports.
3/8 " would be perfect.

x2. 1/8" fittings are really going to throttle back your air flow and you're probably be unhappy with the performance of the system overall.

Any idea what the flow rate would be compared to 1/4 inch ports?
How long would it take to fill a 31" tire?
Is it possible to tap the ports out to 1/4 or just go with a different tank?
Thanks

My gas physics is pretty rusty, but I think 1/2 the diameter=1/2 the area=1/2 the flow. I would shop for a tank with 3/8" outlets.

check out a store like harbor freight or tractor supply, get a cheap air tank and a regulator, work from there.

I'd also like to recommend 3/8" ports. Most pneumatic tools wont run on such a small air line (if you ever plan to use them).
