Finally made it to home depot again and was helped by a retired plumber there that worked in the plumbing section
We figured out what I needed to make my compressor connection
A compression fiting and a copper pipe from a toilet, or was it a sink,,,Im not sure but I did have to cut the end off so I can slide the air line over it

Nothing is tight yet in the pictures.
I have to bend the pipe tomorrow when I do the final assembly.
Maybe tomorrow if I dont go snowboarding

Woohoo!!!!
but thank goodness for pressure release valves!!!!
I fired up the compressor today and watched the psi guage climb until the release valve kicked into action
I had the psi switch hooked up backwards.
I dont have it hard wired yet but it works!
I air my tire down to less then 20 and filled it to 32 in no time at all. alot quicker then the gas station 50 cents pumps
I still have to get the correct hose that connects to the pump.
The one I have dosent have any barbs so the air line wants to slip off, I now have 4 clamps on it just to keep it from blowing off!

This is what happens when you dont have a metal hose at the output connection of the pump, it gets hot and melts!

Melting a hose...Been there, done that.

That's why I use soft copper tube(3/8 inch dia) to go from the compressor to the tank. And have wound the copper tube into a coil.
It cools the air quite a lot and allows the engine to torque move.

Did you use compression fittings on the tube?
What did you use to make the connection to the compresor?
What is that series of fittings going to your compressor?

Tank, psi switch, pressure release valve came from various ebay dealers.
Drain valve,air line, gauges and fittings came from home depot, lowes and local hardware store
The hose is a 300psi rated from home depot

Yes, standard compression fittings, from the ACE hardware. If you notice...those coils are the same size of one of those plastic round containers that bulk blank CD's come in. I think there is nearly 5 feet of copper in that little coil. It really works for cooling.
My compressor came with nothing more than a plug in the holes to keep them clean, all the fittings, brass and copper, are mine. That particular fitting is a pipe thread.
That bunch of fittings contain a couple parts:
A pressure relief valve set at 185 psi(just in case).
A check valve.
Not in the picture is a filter and water seperator. They are down next to the tank, which is under the batteries.
My compressor does not need constant oiling, so I do not use an oiler or coloessor(sp(oil remover)).

the valve is there as a safety measure to keep your system from going over a certain pressure. usually set about 10-20 psi over the working pressure of the system. the switch turns on the compressor by controlling the clutch so the system stays within a certain pressure range. so a 120/150 switch will turn on at 120 psi and turn off when it reaches a 150 psi. with that setup you want a relief valve set for about 160-170 psi.

I installed the illuminated psiguage/on-off switch from Viair that I ordered from qtech today
It was simple to wire up the illumated guage but now its always on when the jeep is on
I want to only come on when the compressor is turned on by the switch. Can I splice the positive guage lite to the positive compressor wires together?
I screwed up the wireing off the compressor and left the hot and ground together and blew a few fuses, I now understand that I cant leave it as factory and have to seperate the hot and ground
I also had to cut into my air hose and splice in a T so it would go to the guage.
I may finish on new years day

Did some more fine tuning today on the OBA
Added a braided hose that comes off the pump to keep things cool and added a air/oil seperator filter

I used a York compressor made a mounting bracket for it has a 5 gallon tank in the back, made my own air manifold for the ARB solenoids and pressure switch.
Used part of the factory wiring and relay in the accessory fuse box to cycle the compressor clutch. Works great, cycles maybe once a day for my lockers on a day long trail run pumps my big ole Pitbulls up in a hurry. I am very happy with it and so far has been very reliable
