Beschreibung
Zusammenfassung:	A liquid vapor separator drain valve includes an outer housing defining upper and lower chambers separated by a divider. An upper housing coupled to the outer housing partitions the upper chamber into inner and outer chambers and defines an upper port for communication with a carbon canister. The outer housing defines an external port in communication with the outer chamber and for communicating with a fill limit valve. Upper and lower valves are positioned in the respective upper and lower chambers such that the valves and upper and lower chambers are arranged in a vertically stacked, concentric manner. The lower valve vents fuel vapor to the upper chamber in a rest position and seals a divider vent passage when liquid fuel reaches a lower threshold. The upper valve vents fuel vapor to the upper port and seals the upper port when liquid fuel reaches an upper threshold.
