For those looking for a good cheep on board air comp. go to the wrecking yard and look at '80's full/mid size American cars for one of these.
They make over 110psi, are very quiet and last forever;)

I agree that the pic was pretty vague.. . However, You can get little air compressors off of mid 80s lincolns.. the continetals had a load leveling system with air shocks and a compressor. you can also get them off of 70s and 80s ford trucks.. not sure which ones specifically but I do remember pulling a while bunch of them off when I worked at a wrecking yard(11-12 years ago)

and last but not least, some soobs came with compressors and tanks built in to the drivers side fender to control the air suspension.. I no longer have the suspension, but I have some pretty nifty ideas for the tank and compressor

Can't you make an air compressor out of an A/C pump? I am almost positive i have seen it done before.....ill try to find out more about it.

This is true harpua. You can use your old clutch AC pump and someone here has done something similar (I'm sure they will step forward so I wont speak for them)

I like the idea of an electric one. Glad to be rid of my AC pump as its a waste of power in more ways then one.

Calebz: The pumps in Subarus that came quiped with pnuematic suspension are neat indeed. Archemitis and myself checked out one on an XT 6. I have no idea what PSI it put out. It definatly looked promising having its own electric motor and air tank.

Anyone fited one of these for other purposes?

Yes, the AC comp is the fastes and best way to go for on board air. It's eazy to do, just cut the rubber lines as close to the unit as poss. then U can tell wich one is the pressure. on the draw side install a drip oiler, and a filter of some type. then run the wire from the cluch to an air compressor switch.
That one in the pic. is from the air ride sys. on a Buick Rivieara, but LOTS of cars and trucks in the '80's had some type of air ride sys. and all the compressors are about the same.

Apparently, early 80's Toyota Corollas had tiny, light weight, self oiling a/c compressors that allegedly put out as much air as the 6 times heavier York compressors. A rock crawling machinist guy I met has one of these in his rig. His reservoir is only a 10# fire extinguisher tank and yet he's got plenty for airing up 37" tires or running tools. His rig is very well crafted so I tend to believe him.
Cool thing about those Cady compressors is they're small, electric, and so abundant...tons at PullaPart.

IF you get a compressor with its own oil supply, you wont' have to use an inline oiler. Older Fords used em, as did some Chryslers. The Chrysler pumps are cylindrical in shape, btu they have a bulge on the bottom which is the oil reservoir.
The Ford compressors are rather large, boxy things, and you can tell by the oil fill and drain plugs on them. These were used in teh 60s and 70s, I dunno how late they used ''em, maybe into the 80s. MY dad's Mustang has one on it. (64 1/2)

I had a '23 Cadillac with a on board air compressor, not sure of the output.
