A fuel injection system includes a fuel supply rail, a fuel injector configured to control the delivery of fuel from the fuel supply rail, and a noise filtering device engaging an upstream end of the fuel injector and/or positioned at least partially within the fuel injector. The noise filtering device defines a fuel passage configured to direct fuel from the fuel supply rail into the fuel injector. The noise filtering device can include one or more of several features including a pocket, a wrap-around shape to conform to the inlet end of the fuel injector, a face-sealing portion, a compression section, and a plurality of parallel restriction passages.

A fuel injection system includes a fuel supply rail having a supply opening. A fuel injector is coupled to the fuel supply rail and configured to control the delivery of fuel from the fuel supply rail through the supply opening. A noise filtering device engages an upstream end of the fuel injector. The noise filtering device has a projecting portion extending at least partially into the supply opening along an axis, and the noise filtering device defines a restriction passage for directing fuel from the supply rail into the fuel injector. A face seal is established at a transverse face adjacent the supply opening.
