An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet. 配置成与燃料箱系统起使用并且根据本公开的个示例构造的主动放泄液体捕集器包括捕集器主体、浮子和导阀。捕集器主体限定第入口、第二入口和出口。第入口流体地连接到燃料泵。第二入口流体地连接到蒸气管线。浮子围绕浮子枢轴可旋转地安装。导阀在打开位置和关闭位置之间移动。浮子的旋转使导阀被推动到打开位置并且使流体通过出口从捕集器主体放泄。
