Abstract
A fuel tank includes a body, a partition, and an opening in the partition. The body has an interior configured to receive and store liquid fuel. The partition substantially divides the interior of the body into upper and lower volumes. The opening in the partition provides fluid communication between the upper and lower volumes, and is located proximate to one of the walls of the body. The fuel tank further includes a fill port and a vent that is coupled to the upper volume away from the opening.
