Abstract: A marine fuel tank includes a "sump" tank compartment. The sump tank compartment projects from and below a main fuel tank compartment. A bottom cover plate, covering the sump, has a large hole in its center in communication with one end of a connection tube. The bottom cover plate for the sump also includes two small holes directly in front of and behind the connection tube, aligned with each other in a direction of travel. These holes allow fuel to move from the main fuel tank compartment of the fuel tank into the sump tank compartment. As the main fuel tank compartment is filled with fuel, the fuel flows to the sump tank compartment by gravity feed through the holes in the cover plate of the sump tank compartment. A fuel pickup tube extends through the connection tube and into the sump tank compartment and its free end is free to move inside the sump tank compartment as moved by the dynamic acceleration forces acting on the fuel pickup tube.
