The red hose is rubber air line, its the same material that a pre made airline is made out of. My local hardware store sells it by the foot so i bought about 30 ft of it and had like a foot and a half left over. Im using airtool oil in the lubricater right now. It seems to be working fine because the recovery filter is collecting a bit of oil in it. Ive used this system almost everyday since i put the it in and all seems well.

As I was being stupid and sold my perfectly working A/C compressor awhile back (my condenser was leaking -> no A/C), I had to get myself a "new" one to do this. I had been wondering if this was doable or not, and after reading this write-up I decided to give it a go. Great write-up


The only difference with my setup will be that I'll put the compressor where the alt. is normally - I relocated my alt. up to where the compressor is usually. I'll need to fab a some sort of a bracket to mount it, but it should be an easy thing to do.

By engaging the clutc do you mean just turning the controls to AC?
I did that and got nothing. Bad pump i assume?

no i installed a toggle switch that takes the place of using the ac controls... the ac controls wont work.., just to test the clutch you can use i jumper wire from from the plug that goes to clutch to the batter and you should hear the clutch click.

This might be a stupid question, but I have never worked with tanks and air lines.

After the T-fitting, the first hose just goes to the front for a quick dissconnect. But when you run the hose to the back, does it go into the manifold and then into the tank, then just run the second hook up from the tank, or vice versa.

The airline runs to the tank, then to the manifold, and from the manifold to the rear connect, but it doesn't matter how you do it. You could put the tank or manifold anywhere on the system, pressure is the same throughout.
