I'm looking into doing this with my Scout.   A potential problem that was
mentioned to me was that  the York compressors have an oil reservoir in
them which provides lubrication when used as an air pump, but the Sanden
pumps didn't.  He said the Sanden was lubricated from the A/C charge
mixed with oil, and it would eventually burn up if used only for air.  Is
this true?  Is a Sanden pump lubricated when used for air?  

I'm considering using a Sanden on the smog pump bracket for the A/C, and
the York in the stock location for the air pump.  This would require the
expense of all new A/C lines and the trouble of running them without
causing interference with any other components.  Is this really
necessary, or will a Sanden hold up to extended use as an air pump?

Thanks for your input.
