ABSTRACT:
A venting control system is provided for controlling discharge of fuel vapors from a vehicle fuel tank. The system includes a vent apparatus mountable in an aperture formed in the top wall of the fuel tank. The vent apparatus is formed to include a vapor inlet opening communicating with an interior region of the fuel tank, a vapor outlet opening, and a passageway interconnecting the vapor inlet and outlet openings. The system further includes a tubular skirt having an uppermost end coupled to the vent apparatus and a lowermost end and a fill-limit valve assembly coupled to the lowermost end of the tubular skirt. The tubular skirt and the fill-limit valve assembly are positioned to lie in the interior region of the fuel tank when the vent apparatus is mounted in the top wall aperture of the fuel tank.
