Fuel Rail Pulse Damper

WARNING: This page is about a different variant/trim than selected.

The fuel rail pulse damper is located on the fuel rail and reduces the 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 if the pulse damper diaphragm ruptures. (The fuel rail pulse damper should not be confused with a fuel pressure regulator; it does not regulate the fuel rail pressure.)
