A fuel rail has a mounting portion with an aperture through which a fastener extends along a central axis. The fastener secures the fuel rail with respect to a support surface. Stacked-layer isolators are positioned on both sides of the mounting portion. Each stacked-layer isolator includes a pair of rings and an elastomer layer positioned between the rings. Each elastomer layer has a pair of opposing contact surfaces respectively contacting adjacent contact surfaces of the corresponding pair of rings. The pairs of opposing contact surfaces of the elastomer layers and the contact surfaces of the pairs of rings are oblique to the central axis.
