A conduit for use with a polymeric fuel tank. The conduit attaches to a fuel tank and includes an outlet port having first retention barb formed from a layer capable of being welded to a fuel tank and a second retention barb formed from a permeation resistant layer. When welded to the fuel tank, the permeation resistant layer may be spaced from the weldable surface of the fuel tank to prevent contamination of any weld joint.
