But you do have the space for one! They fit quite nicely between the A/C compressor and whatever happens to live on the driver-side inner fender. It's somewhat of a tight fit, but not so tight it's a major PITA to install...

An oiler setup is easier than a york install. A york install is easier than the dual-alternator mess. Not sure which one you were referring to...

I keep mine at 115 psi with a safety valve for a portable compressor - it's plumbed in between the hose from the york and the shutoff valve for the air tank, and my T-coupler is between the shutoff valve and the air tank - I have the compressor running constantly when I need the system, and when it reaches the pop-pressure the blow-off valve starts going poof-poof-poof like some big trucks do and vents the excess pressure into the atmosphere. It actually works very good while I'm using up the air, the problem I'm running into right now is that once the blow-off valve pops the tank tries to vent through it too, and the sheer volume of air rushing out does not allow the valve to close as quickly as it does normally - this will be solved on Monday with a 1-way check valve plumbed in between the pop-valve and the tank shutoff. An added benefit is that I can use the pop valve as an unloader to purge all the residual pressure from the compressor and the oil separator after I close the tank shutoff valve, which makes it easier on the compressor clutch next time I engage it. It's not really the ideal way to build an on-board air system, but it's fairly cheap and works pretty decent too.

What i was planning to do with mine was use an air compressor contactor switch with an unloader to control the clutch on the york. I figured that was as close to an actual air compressor system as i would get.

I haven't decided on if i want to run 80 on- 100 offPSI or 100 on - 120 off....

EDIT: Something like this...

Eww, Otahyoni, that thing is so big and ugly - why would you want that in your truck, it would look very weird and out of place!!! There are smaller and much much better-looking switch-things you can use, I have seen them in several people's Jeeps with very big tires, they are like the size of an oil-pressure sending unit, or smaller - I think they are made specifically for 12V use (maybe 18-wheelers and buses, since they use air brakes), unlike that 110V beast you have in that picture...

I did say something like that... i meant in function...

I doubt i would find something like that with a air brake system cause they have a gear driving compressor with a air unloader.... I'll do more looking when i get as far as putting all this together... the first thing is to get the compressor mounted...

EDIT: If i do use something like that picture i'll probably hide it...

Well, especially for you, I just made a phone call - check here:

Air Tanks and Accessories

Take your pick, there certainly is a vast selection to choose from. What compressor are you using, that pretty blue thing?

leece Nevelle made a dual alternator kit for these engines when used in buses and ambulances I have seen two and the alternators are huge almost as large as Class 8 trucks.

That is what I used on the cj5 I used to have. It worked great. The ohio highway patrol just didn't like the 4"od 1/2" wall dom tube i used for an airtank/front bumper. They said it was a rolling bomb. I tried to explain it was not always presurrized but they made me disable it.

with the electric compressors i use, there are one way valves in the heads, so there is no need for an unloader valve.
maybe you can put a one way valve at the compressor outlet??

Well, i could, but i figured it would still have pressure in the head, unless there's a leak...

Also, would a propane tank work for an air tank at 130PSI? Or do i need to hunt down a semi air tank?

pressure relieve. just like the gas compressors run. once it reaches the set psi it opens a valve and bleeds the air off.

yes they will, do a google search on "converting propane tank to air storage" and youll find plenty of info on how to do it "legally" lol

also big rig air tanks are pretty easy to come by too so either way
