Chris-
I purchased the new powerpack in February 2002. The original powerpack was supplied with the kit in April '89.
It's a piece of  JUNK compared with the new powerpack, which was manufactured in China for *I would bet* no more than $50....and at the current retail price of  $1,300, Oildyne is making a few $$$. 
The old 1989 powerpack cost me an untold amount of aggravation....once removed, I was going smash it with a sledgehammer, turn cartwheels over it using a bulldozer and throw what was left in the Atlantic Ocean. Well, I didn't have a sledgehammer or a bulldozer and didn't want to pollute the Atlantic Ocean, so I settled for throwing it in the nearest dumpster.
 
Bill,
Can you tell me what year you bought the original and replacement pumps.  I am trying to get a rough idea when the change to the internals was made.  I have both '95 and '98 era pumps  - one in the plane, one on a test stand. Both are good.  That is, excluding reversed spool valves, which is an assembly issue that occurred in roughly the same time frame, the internal design won't allow all the problems folks complain about.  The change must have occurred prior to ~'95.  I too have tried to get people to look at the pump itself, but band-aids seem to be more appealing to many.
