Abstract

A fuel rail that forms a conduit for pressurized fuel to be delivered to at least one fuel injector. The fuel rail includes an elongated member that is corrugated such that the fuel rail acts as a pressure damper. A method of reducing pressure pulsation in a fuel system is achieved by configuring a fuel of a second configuration from an initial configuration, the second configuration having a first portion and a second portion, the first portion having at least three points defining a virtual plane, the first portion including a continuous surface that intersects the virtual plane at a plurality of positions.
