Abstract
A fuel rail for a fuel-injected internal combustion engine includes an elongated tube having a longitudinal axis, an overall length and a cross-sectional shape along a substantial portion of the length of the tube. The cross-sectional shape is a closed curve, wherein all portions of the cross-sectional shape curve outwardly from the longitudinal axis, and the shape has a non-constant radius. The fuel rail also includes at least one fuel outlet for communicating with a fuel injector.
