ABSTRACT:
A method of forming a gas tank filler neck includes configuring at least a portion of a seamless tubular member to induce a swirl to passing fuel for venting vapors from the gas tank during fuel filling. The configuration may include deep drawing a seamless funnel member, forming a relatively large inlet at one end thereof, and forming a relatively small outlet at the opposite end thereof, the inlet having an axis offset from the axis of the outlet. A filler neck includes a seamless funnel member defining a relatively large inlet opening and relatively small outlet opening, the position of the inlet opening relative the outlet opening inducing a swirl to the fuel being supplied.
