Pulse Damper: Description and Operation

Fuel Pressure Dampener

The fuel pressure dampener is a reservoir mounted to the return line after the fuel rail and the fuel pressure regulator. 
The reservoir dampens pressure pulses by absorbing and releasing a volume of liquid fuel.  This minimizes the pulses in the fuel rail caused by the rapid
opening and closing of the fuel injectors.
