MIke,
I understand it to work as you said. As the engine speed/load increases, the
vac decreases and the regulator closes to deliver more of the fuel to the
injectors. The regulator allows fuel to bypass the injectors at low
speeds/loads, and delivers more fuel in high loads, while the pump itself
does the same work all of the time.
