The VP 44 only needs about 10 Lbs operate correctly.
They do not operate well over 20 or so.
I forget the reasons but hard starting and a few other bad things occur
The mechanical is good for at least 20 lbs and more, which is plenty.
The P Pumps have a pressure relief valve of sorts and do not mind the pulsations.
My concern is the pulsations at lower RPM and pressure on the VP 44.
The pressure needs to be held in check as well as the pulsations because the cam bump runs the mechanical pump.
It may not be as big a deal as I think it is...but I want to get totally ready when I do this conversion.
Who knows I may retrograde to a P Pump in the end.
