This is a cool idea from MSD designed for increasing voltage to fuel pump during boost. Wonder if it could increase voltage the other way? During drop in vacuum?

Hmmm, Maybe what is done is to control a 6 VDC fuel pump with Pulse Width Modulation (PWM)? I used to build robots with permanent magnet DC motors , and I often used 24 VDC on a 12 VDC motor with a PWM motor controller.
