Thanks Lorn,
   That picture clears up a dozen questions but brings to mind one I don't think has been asked.

How can an assembly, so obviously simple, be done wrong?  

After looking at the picture, it appears that the pump could use either side as the high pressure one, as long as one knew which way the "O" ring pointed. Is it possible the "reversed spool valve" was the design intention of the manufacturer? Could we (builders) or Lancair just be putting the pressure valves in the wrong ports? If I had your picture prior to putting the hydraulic system together I think I would have opened the pump up, ascertained which way the spool valve pointed and put the pressure switches in accordingly.
 
Thanks again for taking the mystery out of an unknown!

Mark
