Well The jeep i just bought has ARB's front and rear and I am having a hard time figuring out where i should mount the compressor. I don't want to loose much room if any. And i heard it was bad to mount it under the hood cause of the high temps. Also where did you route the air lines? Thanks in advance.
I had previously installed a K&N Filter that includes a heat sheild. I ended up replacing the filter with a shorter filter (but larger in diameter, so same surface area). That area in front of the filter now holds a compact ARB compressor.
After a Safety Recall was done on my '98 XJ which moves the air bag module from under the drivers seat to beneath the center console there remained a mounting bracket.
I mounted a ViaAir 400 compressor to that mount with rubber feet and routed the actuating poly tubing thru the floor along the frame rail and over to the front ARB.
This keeps the compressor away from the heat and dirt of the engine compartment.
Wired in a pressure switch which automatically starts and stops the compressor to keep a 3.5 gallon pancake air tank pressurized to 70 psi when airing up my tires.
I'm thinking about mounting it in the cargo area in the cubby hole on the pass side. Or possibly under the rear seat. I need to re route the air lines because they are going through the floor right in the middle.
I mounted mine in the front behind the driver side headlamp. I removed the stock airbox.
PS: I have an extra ARB CKMA12, It is the bigger ARB comp that can also pump up your tires; Still in the box with the wiring harness & everything else it comes with. I will give you a good deal if you are interested.

I mounted mine in the cubby hole, out of the way so it wont get damaged if stuff slides around. Its also as far from your ears that you can mount it while still being inside.
I routed the air line under the side moulding and stuck it through a hole under the rear seat.

Poly air lines goes to an pneumatic flip switch and then to the ARB to bleed off air to disegage the ARB.
Also have a 3/8" line going to a 3.5 gallon pancake air tank mounted where the factory spare tire was mounted. The tank has a quick connect to air up the tires.

Interesting, this is exactly what I did except that I used a Viair compressor. There was no room next to the master cylinder due to my ABS equipment so I figured this was the only other spot I could mount it in the engine compartment. I used an Amsoil filter that is larger in diameter and also has an inverted cone built into the front of it.
If I did alot of water crossings or mudding, I might be worried about mounting the compressor in the engine compartment. The heat doesn't really concern me too much though. If you check out the ARB website, the compressor link actually shows a large picture of a guy filling a tire using an ARB compressor mounted in his engine compartment. If they didn't want it mounted under the hood, I don't think they would use that picture to advertise the product. If you want a cooler (or cleaner) air supply, you can always remote mount the intake filter (if the ARB has that option.)
As for routing the lines, I just followed my fuel lines along the inside of the unibody rail. There were actually two extra slots in the plastic clips that hold the fuel lines in place. I used one for the rear locker, and one for the line that's hooked up to my air storage tank. The front air line is zip-tied to my differential vent hose.
I mounted mine behind the drivers side front quarter-panel between the wall of the engine bay and the outer QP. It bolts through the body into the cabin near the drivers feet behind the kick panel. The airline to the rear locker runs with the fuel and brake lines. Front isn't done yet.
I mounted the larger ARB compressor underneath the back seat. I didn’t want it exposed to the outside or engine heat. My back seat sits flat and actually muffles the compressor to the point were you can wisper to someone sitting in the back. I ran the air lines down thru the rubber plug that is conveniently right next to the compressor. Then the air lines are just zip tied to the fuel line to the front and rear.
I'd put it where AshyLarry did - rear passenger side quarter panel behind the trim in the trunk area. Stick a pancake tank where the stock spare was and you're golden!
I used 1/4" diameter poly tubing for everything - no air lockers, but I have setups for tire refilling and my airhorn. I actually snaked the poly tubing straight up the roof under the headliner and you can't even see it, I figured it'd leave bulges at the crossmembers but it hasn't yet.
I have the ARB CKMA12.... It's configurable. If you loosen a couple of screws, you can rotate the mounting plate and the storage tank such that it fits perfectly down inside the passenger rear quarter. You will not have to hack up the cubby in the plastic cover because it sits down below it.
Then I ran the air line to the rear locker (I only have a rear) just like austinaubinoe did. It goes out the bottom of the plastic cover (cubby), under the carpet, across and under the bulkhead that the front of the rear seat sits on, then up the passenger side and through a rubber plug that exits the tubing just in front of the left rear wheel.
I then ran a 3/8" line from the tank through a hole in the bottom inide of the rear quarter to a "Y" fitting. Where the line splits at the "Y" I ran another length of line to the rear bumper and one to the front up the inside of the drivers frame rail (for lack of a better term).....
Then I made two custom brackets that mount quick disconnects to the front and rear bumpers and I carry a 10' flexible airline in my recovery bag as well as a blowgun and a tire chuck. I can fill my tires (32's) from 15 psi to 30 psi at exactly a minute each tire.
I'm very happy with the setup. It won't run air tools as the storage tank is about 1/2 the size of a soup can, but I used it to blow up a small infaltable pool for the kids last week. Took awhile tho.......
i have the larger arb compressor mounted behind my front bumper, below the radiator. it is hidden & works fine so far, although i worry about it sucking up water when driving in the rain or splashing through deep water / mud.
