I'm basically sold.  How do I regulate the pressure from 40 psi pump(s) at 26 psi?  Can I do this halfway at a time (retain the engine driven pump and plumb the boost pump in series)?

I'm still short a pressure regulator and a design criterion ... Jim S.

Various RV-x drivers that use the O-320-H-series engine have deleted the front mounted mech. pump & gone to 2 elec. pumps (low pressure carburated systems).

The engine driven fuel pump (bolted to a hot air cooled engine) with a gascolator mounted down where the hottest air exits and near red hot exhaust pipes (standard aircraft practice) is the dumbest fuel system layout I can think of.  And they wonder why they are so prone to vapor lock........
 
Two electrics sound like a fine idea to me.
