For any air compressor system you require a air tank for storing the first burst of air any air tool needs when it first starts. In a jeep wrangler there is a larger area under the body between the driver seat and rear axle where a tank can be mounted. In another vehicle there mounting location will probably be different.

The air tank I chose is a old Ansul Redline cartridge fire extinguisher the 30 pound model that I got from a local fire extinguisher shop for free. I measured its volume to be around 6.7gallons. To attach the tank to the jeep I used to 12" sections of 1" square tube that I welded to the side of the tank. The Ansul tank is think enough that you don't need to worry about its structural strength.

If your near a auto wrecker that specializes in tractor trailer or large trucks you can easily get a air tank with the appropriate fitting and ports for about $20.
