Abstract
A molded fuel filler pipe for use in automobiles, in particular cars, comprises a one-piece structure which is blow molded. The conduit produced in the blow mold has a smooth edged tubular portion and a bellows portion which is molded at the same time. By deforming the bellows portion, flexibility in the relative location of the two ends of the conduit is provided. This eliminates taking two separate pieces and joining those pieces which may give rise to fuel vapour permeation through the joints.
