A fuel pulsation damper (sometimes referred to as an FPD) is a device used to regulate the oscillation of fuel caused by the injectors opening and closing. This pulsation creates a 'ripple' effect that disrupts adequate flow to the fuel injectors and result in loss of power across the RPM range. This damper uses an internal spring and diaphragm to absorb oscillations and smooth fuel rail pressure to maintain a consistent fuel flow to the injectors.
