Fuel pulse dampers work in tandem with the fuel pressure regulator to further control fuel pressure in an EFI system, smoothing out the pressure pulsations caused by injectors opening and closing and by the fuel pump operating — pulsations too fast to see on an analog gauge but that can still disrupt fuel delivery.
