Here's what you do:
- Attend a "LOST" West event (like Big Bear) and win a cargo rack from All-J.
- Buy a discontinued compressor from Checker for $25.

Jeremy, do you have a plan for hooking the MV50 up to that 2 1/2 gal tank? I assume that you'll need to work in some sort of regulator, and a pressure switch to turn off the compressor when the tank hits a certain pressure? Or are you assuming that the tank will never fill while you're filling your tires (not enough flow from the MV50), so you can just shut the compressor off when you're done airing up? If you end up mounting the compressor inside the cabin, how will you get enough juice to it? (The wires powering the cig lighters obviously won't work.)
I'll be very interested to see how you end up making this work. And it would be awesome if Clint, or someone else who has built a "fill all four tires at once" contraption could repost the instructions on how to do it.
I have a tendency to carry tall things, so a permanently mounted shelf is unfortunately not an option, as much as I love All-J's creation. I already have the compressor (as I mentioned before, $59 from Pep-Boys.)
Tank will end up mounted in the cargo area, still trying to figure out the best way to mount it without drilling holes in the floor. I'm thinking about drilling out the rivets for the cargo tie-downs, placing a metal strap of some sort over the holes where the rivets were and then re-attaching them with bolts or rivets. I'll mount the tank to a board and attach the straps to the board as well. How does that sound to ya'll?
The MF-1050 (same as the MV-50, just branded MasterFlow instead of SuperFlow) will be mounted in the cargo area in front of the tank if there is room, or under the rear seat or driver's seat. I'm going to remove the quick disconnect nozzle from the compressor, cap the hole it was in, remove the pressure gauge and install a 1/4" "M" style disconnect (the most common style, see image 3) where the gauge was. The reason for moving the connection from the side to where the gauge was is so it will take up less room. I'm not going to be able to see the gauge with it under the seat anyway. Power will come from the battery through the firewall and will be switched by a relay which is controlled by a switch on the dash. Eventually (probably when I have the money for a rear ARB) I'm going to add Viair's installation kit (img 8 ) which includes an 85psi on/105psi off pressure switch and a dash mounted gauge and toggle switch. For now I'm not worried about the gauge and pressure switch, as I've installed a 115psi blowoff valve (img 5) in the tank, and the tank is rated to 150psi (the compressor has a max working pressure of 120psi.) I'll just shut the thing off when I hear air coming out of the blowoff valve.
The compressor and tank will be connected together using 3/8" ID hose rated to 300PSI (Home Depot and Lowes are selling 50' of this in bright orange for $10, so my hose will be very visible. I'm of course going to cut it down to the required length.) It'll have an air tight coupler (image 2) at the compressor end so I can pull it off of the compressor if need be without losing air. The other end will have a quick disconnect fitting (img 4.) It will attach at the tank end to another coupler (img 1) so I can remove the hose from the tank without depressurizing the tank.
Also attached to the tank are a drain cock (img 6) for draining moisture out, another coupler (img 1) for attaching tool and a hose for filling tires, a pressure gauge (img 7) and eventually the pressure switch from Viair's installation kit (img 8.)

The whole setup should look like this when I'm done:
At some point I'll also add a quick disconnect in the front grille so I can have better access to the air (without having to open uo the swinggate.)
I may end up building a box around the tank and/or compressor, depending on how vulnerable I feel the connections on the tank are and how noisy the compressor is. If I box the compressor I'll add a PC fan or two to the box to help keep it cool.
I'm going to work on getting the compressor installed tonight and hopefully I can also do a pressure test.
Oh, and during my searches I came across all 3 links you posted. Good info though.
I'll keep everyone updated as I progress.
UPDATE: Well, I didn't get anything permanently installed tonight, as one of the fittings broke off in the tank and it took me about an hour and a half to get the remains out. I found a mounting location for the compressor though. It will go under the passenger side rear seat, where the factory jack was stored (it doesn't even reach the frame now anyway.) I had to remove the little carry-handle (not that it matters anyway) from the compressor so the seat wouldn't hit it when folded down. Interestingly it would not fit under the driver side rear seat with it folded down. I'll rig up something to secure it to the bolt hole that the jack carrier bolt went into.
I also hooked the compressor to the tank outside the Jeep and ran it up to 100psi. It held that for over 30 min without any loss and then i separated the tank and it's going to sit in the garage until I get home from work tomorrow. Hopefully it won't lose anything.
