Claim Text:
1. A fuel rail assembly for supplying fuel to at least one fuel injector, said fuel rail assembly comprising: a hollow fuel rail extending along a fuel rail axis, said fuel rail having a first fuel rail end disposed along said fuel rail axis, a second fuel rail end disposed along said fuel rail axis, an inlet for introducing fuel into said fuel rail, and at least one outlet for dispensing fuel from said fuel rail; a first end cap closing off said first fuel rail end; a second end cap closing off said second fuel rail end; a fuel rail damper disposed within said fuel rail between said first end cap and said second end cap and extending along a fuel rail damper axis from a first fuel rail damper end to a second fuel rail damper end for damping pressure pulsations within said fuel rail; and a fuel rail damper support for positioning said fuel rail damper within said fuel rail, wherein said fuel rail damper support comprises: an attachment section for fixing said fuel rail damper support to said fuel rail damper; a biasing section that applies a biasing force to said first end cap to urge said fuel rail damper axially away from said first end cap and to prevent movement of said fuel rail damper along said fuel rail damper axis within the fuel rail; a fuel rail damper support base wherein said attachment section extends from said fuel rail damper support base; and a positioning arm extending from said fuel rail damper support base, said positioning arm including a locating surface which abuts said first fuel rail damper end such that said first fuel rail damper end is an endmost distal section of said fuel rail damper.
