ABSTRACT:
A filler tube assembly for use in a system having vapor recirculation includes a check valve having a flapper that is responsive to the viscosity of fluid around the flapper and/or a differential pressure across the flapper. The assembly also includes a nozzle chamber formed in the filler neck that has a constant diameter to ensure consistent vacuum generation regardless of fuel nozzle length.
