<p>A fuel system (28) includes a filler neck (34) coupled to a fuel tank (12), a fuel vapor discharge apparatus (36) arranged to conduct fuel vapor from the fuel tank to a fuel vapor treatment cannister (30), and a fuel vapor recirculation apparatus (38) configured to conduct limited amounts of pressurized fuel vapor from the fuel vapor discharge apparatus under certain conditions during refueling of the fuel tank to a fill cup (52) at the inlet of the filler neck (34) to minimize introduction of outside air into the fuel tank through the filler neck during refueling. <IMAGE></p> |
