So, this is one I'm particularly proud of.
A few weeks ago, I ordered the ARB CKMA12 air compressor as a faster, more efficient replacement for my cheap and slow Viair portable compressor. My original plan was to mount it in front of the factory air box under the hood, but once it was delivered, I found that mounting it in that manner would make it so that I'd have to completely remove the assembly to replace any of the bulbs up there. I didn't really like that idea much, so I started thinking about other ideas. I thought about mounting it on top of the wheel arch, but when I did a test fit, it looked really messy. I looked for about an hour for a place to mount it elsewhere, but I was unable to find anywhere that I liked. I sat on it for a few days, trying to think about a good solution. Then, I was walking around my local sporting goods store and found this Pelican-style case on a clearance shelf.
As it turns out, the compressor fits in there perfectly. And I did a test fit of a spot in the bed, and it fits in there really well. So here's what I did...
I gathered up all the necessary parts and started modifying the box. First, I removed the handle and took out the pressure relief valve. Then I put the compressor mounting bracket in the case, lined it up, and drilled the holes.
I had to route an intake hose to the outside of the box, because the box itself is pretty restrictive to air flow. So I drilled out the pressure valve hole with a unibit and pushed a 1/4" female fitting with a hose barb on one end. The ARB compressor has a filter with threads to fit a 1/4" union, so I sealed it with teflon pipe tape and threaded it in. I now had a solid intake from the outside. Then I drilled a large hole on the side to accept the quick release hose connection.
Next step was setting up the fittings on the compressor itself. I installed a 90* elbow on the outlet and screwed the pressure switch adapter to that. Then I had to figure out a good way to route the air from the outlet to the side of the box. I hung around my hardware store for about half an hour trying to come up with a good solution. I was checking out some options on my phone, and found a forum where someone had asked about running an air line. As it turns out, stainless braided hose for a faucet works perfectly well as an air line. I bought a 16" section, some fittings to adapt the hose to 1/4" fittings, and assembled it on the compressor. Then I installed a 90* elbow with a hose barb on the inlet side. Now I was ready for the mounting.
I drilled four holes in the bed just under the Hi-Lift and sent the bolts through the bracket, then the case, and into the bed. I had a friend help me tighten the hardware, and I installed the compressor on the mounting bracket. I ran a piece of 3/8 fuel line hose between the inlet on the compressor and the hose barb attached to the intake filter, securing it with hose clamps.
I then connected the stainless line to the quick release connector through the hole I drilled earlier. Ta-da! I now have a hard mounted air compressor in a good, accessible location that looks really clean. I'm super happy with how it turned out. I still need to wire it, but that's a fairly minor procedure.
Here it is in it's new home.
The intake filter attached to the top of the case.
The compressor all set up.
Super excited to use it fir the first time!
