The fuel system has a recirculation line connecting a fuel tank to a fuel fill inlet. An ejector is positioned within the recirculation line, and a valve is positioned within a drain line fluidly connecting the ejector to the fuel tank. A pressure sensor is positioned to measure a pressure associated with the drain line between the ejector and the valve. A controller is in communication with the pressure sensor, and the controller configured to, in response to initiation of a refueling event, determine a state of the valve based on the pressure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for controlling flow in a fuel recirculation line","description":"A fuel system, a method of fueling a vehicle, and a vehicle are provided.
