Abstract
A fuel communicating assembly including a base having a wall disposed about a longitudinal axis. The wall having a surface exposed to the longitudinal axis. The surface defining a chamber. The wall having an end that defines an aperture to the chamber. The assembly further including a component having a housing. The housing having an exterior surface. A portion of the exterior surface disposed within the chamber. A metallic member having an inner surface and an outer surface contiguous with the exterior surface of the component. The outer surface is contiguous with the surface of the wall so that the portion of the exterior surface of the component is retained within the chamber and the aperture of the chamber is hermetically sealed. A method of retaining a component within a base is also described.

An assembly comprising:
- a base having a wall disposed about a longitudinal axis, the wall having a surface exposed to the longitudinal axis, the surface defining a chamber, the wall having an end that defines an aperture to the chamber;
- a component having a housing, the housing having an exterior surface spaced from the surface of the base, a portion of the exterior surface being disposed within the chamber, the component comprising at least one of a fuel rail end cap and a fuel pressure damper;
- and
- a metallic member having an inner surface and an outer surface, the inner surface having a lower surface roughness than the surface roughness of the outer surface, the inner surface being contiguous with the exterior surface of the component and the outer surface being contiguous with the surface of the wall so that the portion of the exterior surface of the component is retained within the chamber and the aperture of the chamber is hermetically sealed, the metallic member having a tubular wall having a cross-sectional area approximately equal to a cross sectional area of the component, the tubular wall including:
- an inner surface and an outer surface;
- a sleeve portion proximate the base, the inner surface and outer surface of the sleeve portion being substantially parallel to the longitudinal axis;
- and
- a lead-in portion extending away from the sleeve portion and being contiguous therewith, the inner and outer surfaces of the lead-in portion curling away from the longitudinal axis as they extend away from the sleeve portion.
