Abstract
A vapor separator includes a fuel pump, and a container at least partially defining a fuel reservoir to hold fuel and a pump chamber to hold the fuel pump. A closure is carried by the container to close the fuel reservoir and at least partially defines a vapor chamber above a level of fuel in the fuel reservoir and in fluid communication with the pump chamber. A vapor vent device is carried by the closure to allow fuel vapor to vent out of the vapor separator from the vapor chamber and prevent liquid fuel from flowing therethrough when the vapor separator is declined.
