this write up is so you can use the stock A/C compressor that is on the 2.9L this may work on other models but I can not say for sure.
When looking at this picture the a/c pump manifold on the bottom is the intake and the a/c manifold on the top is the exhaust for the pump.
lets start from the intake side. you will start with an intake filter I used I think a PCV breather for euros at advance auto. From the filter I used a 3/8 nipple to hook the filter to the oiler from the oiler I took a piece of 3/8 air hose to the hose I had made for the intake manifold. that completes the intake of the onboard air system. Now for the exhaust which is what will fill your tank. I used the other hose I had made went int a "T" fitting where the pressure switch is then I went from the "T" to the air/oil separator from the separator I took some hose all the way back to a "X" that is mounted on the tank that also holds a pressure guage and an air chuck. that pretty much completes the install. Now back to the pressure switch. This pressure switch is from an old air compressor that I had it tturns off the power to the pump when the pressure in the tank reaches 100psi, and turns it on when it drops to 80psi. I used the original button to control the main power to the compressor to maintain a factory look. in the future I will install an in dash pressure guage. most of these parts that I have used I have gathered of the last year so I can not give a cost on the entire project, here are the things I just bought. The 2 hoses I had made up cost $35, I bought 50ft of goodyear hose from Harbour freight for $18, I probably have $20 wrapped up in fittings I bought the tank from HF for I think $15 that is all I can remember right now. here are some more pics if there are any other questions feel free to ask, god knows I ask enough.
