The second high-pressure pump allows an even higher flow In other words, two identical pumps in series can flow the volume of one pump but at twice the pressure. A forced induction engine also requires more fuel to support HP developed in the cylinder but lost to the work required to drive the compressor helping to make the extra power. There are basically two types of pumps used in automotive fuel systems, those that are pressure limited, for use with a static (non bypass) regulator, and those that are not pressure limited, and which must be used with a dynamic (bypass style) regulator. 2.
