Abstract

A fuel rail assembly comprising a fuel rail and a damper assembly in the fuel rail. The damper assembly includes a damper having an end and an inner surface defining a cavity, and a sealing member at least partially received in the end and bonded to the inner surface to substantially seal the cavity. The sealing member is preferably a metal wire that includes a sealing portion bonded to the inner surface to substantially seal the cavity. The bond is preferably formed by induction brazing, and the sealing member is coated with copper to facilitate the brazing. The invention also provides a fuel rail assembly comprising a fuel rail having a longitudinal axis and an inner wall. A damper assembly in the fuel rail includes a damper, and a spring locator coupled with the damper, the spring locator having two positioning portions outwardly biased to engage the inner wall of the fuel rail and position the damper assembly axially in the fuel rail. The spring locator is preferably a metal wire. Most preferably, the sealing member and the spring locator are the same device that both seals the damper and locates the damper assembly inside the fuel rail.
