Apparatus and method of assembling an interior fuel systems component suitable for immersion in liquid fuel in a tank to an exterior component of different material weldable to the fuel tank. The exterior component is preferably formed of HDPE having a hardness in the range of about RR-40 to RR-80 and has an array of projections extending therefrom. The interior component has a corresponding array of radially extending slots having barbed edges for push on connection to the projections. The slots permit sliding movement due to material swelling of the projection on the barbs without loosening of the connection. The internal component is preferably formed of material comprising a member of the group consisting of Polyamide, Polyketone and Polyphenylamide and having a hardness in the range of about R112, such that the barbs deform the lugs to maintain the connection.

Assembly of fuel system components on a fuel tank

A fuel vapor vent valve and method of making same for installation in an access opening of non-metallic fuel tanks. The valve body is formed of material not weldable to the tanks and an annular seal member formed of resilient material seals between the body upper portion exterior to the access opening and an overmold formed of material weldable to the tanks for retaining and sealing the valve thereon. In one embodiment the seal member is received in a groove and retained by a ring; and, in another embodiment the seal is formed by potting material cured in the groove prior to the overmolding.
