Zusammenfassung:	Disclosed herein are liquid containment systems, methods for making such systems, and vehicle fuel storage systems having vapor recirculation capabilities. Presented is a liquid containment system forstowing hydrocarbon-based liquids. This system includes a vapor canister coupled to a liquid container to receive hydrocarbon vapor from the container. A fill conduit coupled to the container has anopening for receiving a fill nozzle. A vapor recirculation transmits vapor from the container to the fill conduit. A multi-stage check valve, which is coupled to the container and recirculation conduit, has a housing and a plunger with a bleed hole. The plunger seats against the housing such that vapor passes from the container through the bleed hole to the fill conduit via the recirculation conduit. Responsive to increased in-tank pressure, the plunger unseats from the housing such that vapor passes through the bleed hole and around the plunger to the fill conduit. 本文公开了液体容纳系统、制造该系统的方法，以及具有蒸汽再循环能力的车辆燃料储存系统。给出了种用于收纳烃基液
