Hi Mark,
Yes, I can tell you, but doubt it will be too
meaningful.
My regulator does have a reference to the manifold -
but, this apparently only causes the pressure regulator to react to positive
(boost) manifold pressure - in otherwords while under boost
pressures the regulator will increase fuel flow to the injectors by increasing
pressure.It apparently does not regulate the fuel
pressure at normal manifold pressure ranges.
But, in any case my pressure regulator keeps the fuel
pressure at 41 psi with one pump on and it increases to 43 with both pumps
on. Again,changing manifold pressure does not affect my fuel
pressure.
I intend to swap it out (someday) for one that is a true
manifold referenced regulator - but, sigh, just always seems to be something
else to do - and it has worked for me for 10 years. But, I could probably
get an even smoother idle if I swapped it out.
I would say 41-43 psi would be a reasonable
setting.

Ed,
Can you tell me what pressures you're seeing on your fuel pressure at
idle, mid-range, and WOT? Also, please verify that you set the fuel
pressure with engine stopped and fuel pumps ON. What should the
fuel initial fuel pressure be set at for our purposes?
Thanks,
Mark S.
