[V8] PS pump interchange-ablity

Thu May 1 09:45:43 PDT 2008

I can't think of a better resource for these pumps than Rick at  
www.importpartsspec.com.
Before he started Import Parts Specialists, he was a pump rebuilder  
supplying the after market.  He knows all there is to know about  
these, and can (could?) easily and cheaply rebuild them.  The problem  
is that he quit rebuilding them a long time ago, and may have run out  
of replacement bearings which were hard to source.  Seals are still  
easy to get. WIthout replacing the bearings, the front seal will not  
last long, and this is the reason so many people have trouble with  
their pumps after only replacing the seals.  There is contact  
information on the web page, and he can tell you if he can rebuild  
yours or not and can probably also get you a reman unit from a  
different supplier in any case.

It would be well worth your time to investigate this resource before  
attempting to hack in a different pump.
