1. A fuel rail mounting arrangement comprising:
a fuel rail having a mounting portion; an aperture in the mounting portion of the fuel rail; a support surface; a fastener extending through the aperture along a central axis, the fastener having a first end and an opposed second end, the fastener configured to secure the fuel rail with respect to the support surface; a first stacked-layer isolator positioned on a first side of the mounting portion, compressed between the first end of the fastener and the mounting portion of the fuel rail by tightening of the fastener, the first stacked-layer isolator including a first pair of rings and a first elastomer layer positioned between the rings of the first pair, wherein the first elastomer layer has a pair of opposing contact surfaces respectively contacting adjacent contact surfaces of the first pair of rings, and wherein the pair of opposing contact surfaces of the first elastomer layer and the contact surfaces of the first pair of rings are oriented oblique to the central axis; and a second stacked-layer isolator positioned on a second side of the mounting portion, compressed between the mounting portion of the fuel rail and the support surface by tightening of the fastener, the second stacked-layer isolator including a second pair of rings and a second elastomer layer positioned between the rings of the second pair, wherein the second elastomer layer has a pair of opposing contact surfaces respectively contacting adjacent contact surfaces of the second pair of rings, and wherein the pair of opposing contact surfaces of the second elastomer layer and the contact surfaces of the second pair of rings are oriented oblique to the central axis. |
