ABSTRACT:
A filler neck includes an internal tube that is movable to open and close the filler neck. The movable tube is formed to include a fill passageway that extends therethrough and is configured to deliver fuel from a fuel-dispensing nozzle to a vehicle fuel tank when the filler neck is open. The "moving" fill passageway is closed when the filler neck is closed and opened when the filler neck is opened. An inlet opening into the moving fill passageway is formed in an outer end of the movable tube and an outlet opening for discharging liquid fuel from the moving fill passageway for delivery to the fuel tank is formed in an inner end of the movable tube. A fill passageway closure member is appended to a filler neck conduit and positioned to lie in a filler neck vent passageway in spaced-apart relation to the mouth of the conduit. The movable tube is positioned in the conduit for movement in the vent passageway to cause the fill passageway to engage or disengage the fill passageway closure member so as to control opening and closing of the filler neck during the after refueling.
