1997 XJ 4.0L. I'm looking to get OBA to air up no bigger than 33" tires and run tools (~90-100psi). So, I figure with a proper compressor a two gallon tank will do.

Does anybody know a good mounting/place to put the tank and compressor?

I was thinking about removing the rear passenger side interior panel and mounting everything there. I would prefer not placing the tank under the XJ, but open to options. Any inputs?

I pretty much only find post about turning the A/C into OBA. Not what I want to do.

 

I think it's pretty sick when the gas tank is tucked into the cargo
and the air is mounted where the old spare tire goes and the nozzle is put through the stock gas tank fill door
I've seen it done that way a couple times. looks awesome I cant find a pic tho

 

I mounted mine where the stock spare goes, up high so it doesn't really affect cargo area since things can easily be packed under it.

 

You won't fit any substantial size air tank behind the paneling, however the compressor could probably fit depending on size. I mounted my tank in the stock spare location, I cant remember exactly how much but I think its like 2.5 gallons.

 

You can check out my build to see how I fit everything in that space.

I used a Wilkerson regulator/separator for the 90psi needed for the lockers, this is monitored on the gage in the front console. There is another glycerin filled gage out back to show total psi.

I have a small manifold with 6-8 ports for the air line that runs to the front bumper and rear air chuck.

I made the shelf for the tank out of a piece of scrap metal so it would sit flat. Someone pointed out that the drain in the bottom should be positioned at the lowest point, so I modded it some.

I can run air tools in short bursts, enough to remove lugnuts, etc. If I had a continuous duty compressor it might help, but I think you'd have to add more volume to use air tools like you would in a garage. But for trail fixes, etc it does its job well.

This is an older pic before I put the valves in, but you get the idea.

 

I'll copy yours. Thanks for the input, especially the picture.

 

Have thought about onboard air for the cherokee for some time. Most all systems are a drop in which eats up cargo room in an already limited cabin. When I go out normally have the family in tow along with out camping gear and or bikes on the Jeep which makes it really tight.

Adding a compressor would be very cool and add utility to the Jeep. One area which I thought would be ideal for onboard air is to have a sealed rear bumper as your air tank especially a cut an fold version. With the new configuration behind the passenger side bucket you could cut that out mounting the compressor feeding the integrated bumper/airtank. Wish I had pics. If someone wants the design for a build I'd be happy to share.
