Actually, since the liquid is essentially incompressible - the
pressure at one point in the line is the same at all points when
there is no flow - as you know. Of course flow will cause some
pressure drop through restrictions, etc. But, you could have the pressure
regulator in the rail before the injector and it would still regulator the
pressure the same way - by releasing fuel back to the tanks.
However, You are correct - for our usage I also firmly
believe the best place for the fuel pressure regulator is after the
injectors.

Ed, I must have mispoke to give this impression, I thought the pressure reg
HAD TO be last in line to maintain pressure in the fuel rail?

If the pressure regulator is place before the injectors then
there is less fresh fuel flowing through the
rails.
