Abstract
A fuel rail assembly includes a hollow fuel rail extending along a fuel rail axis and includes at least one outlet for dispensing fuel from the fuel rail. A fuel rail damper is disposed within the fuel rail and extends along a fuel rail axis from a first fuel rail damper end to a second fuel rail damper end for damping pressure pulsations within the fuel rail. A fuel rail damper support is included for positioning the fuel rail damper within the fuel rail. The fuel rail damper support includes an attachment section for fixing the fuel rail damper support to the fuel rail damper and a biasing section that applies a biasing force to prevent axial movement of the fuel rail damper within the fuel rail.
