CA2366077
A fuel tank filler neck assembly includes a resilient seal interposed betwee n a flanged opening in the fuel tank and a filler pipe. The seal is preferably molded or otherwise manufactured from an elastomer, which provides an effective barrier to the permeation of fuel vapors. The seal has a plurality of ribs that assist in bore retention as th e filler pipe is inserted through the flanged opening. An alternative embodiment includes a ribbed resilient seal with a metal insert contained within an elastomeric matrix. The metal insert aids i n the alignment and installation of the seal. In all embodiments, the seal provides a resilient and secure leak tight joint for use in metallic and polymeric fuel tanks.
