ABSTRACT:
A fuel tank filler assembly includes a filler neck configured to receive a fuel supply nozzle. The filler neck includes a one-piece seamless funnel member having a tubular body configured to swirl supplied fuel and reduce vapor escape. The tubular body includes integrally formed threads for receiving a gas cap. The funnel member defines in off-set axial relation a relatively large inlet opening adapted for attachment to a receptor for the nozzle and a relatively small necked down outlet opening adapted for attachment to the inlet of a filler tube. The filler tube is in communication with the fuel tank. A method for manufacturing the fuel tank filler neck is also disclosed.
