Hey Bill,
 
I appreciate all the help I can get - different insight/experience is what makes sharing information on this list so useful.  It certainly seems that the return capability of this regulator could be less than required to properly regulate pressure referenced to manifold.  I had assumed that since MSD advertised their High pressure pump and regulator together that they would work together.  And the regulator may indeed increase fuel pressure/flow if presented with boost pressure (above ambient) - just don't know since I don't have a turbo.
 
Thanks again

Ed, There are two parts to this equation. First: Does the regulator flow enough by itself. Second: and almost as important is the plumbing itself. Some people will use very small return plumbing. That plumbing can restrict flow, keeping the fuel presure high. Another thing for the new people to remember, be sure your return switches with your tank valve. There have been accidents where the return flow wasn't switched and the tank ran dry. (Always on final of course)

All my plumbing is 3/8” ID aluminum tubing, hose and fittings. My fuel valve is 6 port that switches feed and return to the same tank simultaneously. One less thing to wary about. I know people have designed systems that rely on them remembering when and which switch to turn for proper fuel management. I’m not that sharp :)
