Here is what I went with:

The explanation is in the captions. My original Dana compressor would pump up the tank to 140 PSI, but made an embarrassing amount of noise doing it. The new Viair is much quieter and does the job in less time. It is a 100% duty cycle unit and specs can be found on Viair's web page. There are some 25% and 35% duty cycle units that actually pump at a higher CFM rating, that would also be more than adequate since they do not operate constantly.

Jim K. also has a (I believe Firestone) compressor on his site that is a bit larger and will pump up the system faster, if you feel you need that.

I have put a considerable amount of time into my air system, including JR Slaten "Power Level II" dash valves, an electronic regulator, from Jim B. an adjustable safety valve, from Jim K, and numerous nuts and ferules, to stop annoying leaks.
