Regulator is after the fuel rails -- so the fuel is fed to the front of the passenger rail - out the back - looped to the front driver rail - out the back to the regulator mounted on the firewall - where it returns to the tank.
I ASSumed the fuel was moving continuously through the system... only "stopping" / or "slowing" as required to build pressure (the regulator - doing it's job ala a thermostat on the coolant side of things).
If the pump is whirring away without any fuel movement -- then wouldn't we have another issue --- CAVITATION?
