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