The rubber hose seen in the picture comes off the discharge side of the compressor (clearly labeled with a D). For now it's held one with a simple hose clamp. I wasn't sure if that would work but so far it has been working flawlessly. It then goes around the other side of the air box pictured here
The air goes through a check valve first. This prevents the air from backing up when the compressor clutch shuts off. It's important this is the first thing after the discharge and it's very important that it is positioned with the arrow facing the correct direction for the flow of air. I read a thread where a guy blew up his compressor because the check valve was oriented the wrong way. These compressors are supposed to be capable of 300-400 PSI. Next in line is a pressure switch that turns off at 120 PSI and on at 90 PSI. These two parts are the only ones I ordered and didn't purchase locally. I got both off amazon. I believe the check valve is a viair part.
The air then goes down under the radiator and to a T with a quick connect by the winch. I made a simple little bracket that is bolted to the winch plate to hold it.

It then runs down the drivers side frame rail and follows the gas line up by the gas tank. I then ran it up behind the rear tire and used a rubber grommet in the fender to run it into the tub. The grommet was already there with the hardtop wires running through it.
It then goes into the 5 gallon tank I got at harbor freight. I used another T fitting and put another quick connect here.
I also left the gauge that came on the tank. The only things left to do are to install an intake filter on the compressor. With the amount of grease I put inside I don't think it's a huge deal but I do want something on there for some piece of mind. I also was going to put a grease nipple in the oil fill plug on the compressor but once I mounted the compressor I realized the it was facing the engine and would be impossible to get a grease gun on. What I will probably do it take it off once per year and shove some more grease in it. The compressors are quite cheap at junkyards so if it blows up I'm not out much. Plus everything is already set up so I could just plop another one in there. The time consuming part is figuring out what fittings are needed. I would post what I used but it's pretty different depending on your particular system.
I also had an idea to make a heat exchanger coming off the discharge with some copper tubing if the rubber ever gives me trouble due to the heat. It hasn't yet so I am going to leave well enough alone for now. I ran it pretty hard at Schoodic last weekend (aired up like 4-5 jeeps) and it worked flawlessly. Overall I'm really happy with it. It's much faster than my home compressor and runs air tools pretty well. It's supposed to put out around 7 CFM and if you need more just step on the gas.

This is a rough diagram I drew up of the whole system to give you an idea of the big picture.
One of the things I sprang for was expensive rubber hose. I wanted the highest temp rating I could find. I found a 50ft roll at Lowes that was rated to 200 degrees F. I figured that was the best I was gonna get and so far it's working well
