Fuel Pressure Pulsation Damper: Description and Operation
Primary Fuel Rail (Delivery Pipe) And Injector
The pulsation damper, which is built into the primary fuel rail, is used to reduce the pressure pulses from the fuel pump and provide a more constant fuel
pressure to the injectors. As a result, fuel pump noise is also reduced.
