Fuel Pressure Pulsation Damper: Description and Operation
Pulse Damper
Pulse Damper
The fuel rail pulse damper located on the fuel rail reduces fuel system noise caused by the pulsing of the fuel injectors. The vacuum port located on the
damper is connected to manifold vacuum to avoid fuel spillage in the event the pulse damper diaphragm were to rupture. (The pulse damper should not
be confused with a fuel pressure regulator, it does not regulate fuel rail pressure.)
