A fuel tank filler neck is provided to reduce the escape of gasoline vapor from an automobile fuel tank system and is leak tight. The filler neck is configured to receive a fuel supply nozzle. The filler neck includes a one-piece seamless funnel member having a tubular body and an elongated tubular member. 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 an elongated tubular member. The tubular member is adapted to be in communication with the fuel tank. A method for manufacturing the fuel tank filler neck is also disclosed.
