1. An apparatus for preventing fuel spillage on a marine vessel, comprising:

  • a vent line coupled between a fuel tank and a vent port of the vessel;

    a valve assembly coupled within the vent line for preventing an overflow of fuel from the fuel tank from passing through the vent port into the water, and defining an inlet port coupled in fluid communication with the fuel tank, an outlet port, and a first fluid passageway between the inlet and outlet ports, and including a first valve member preventing the flow of fuel through the first fluid passageway when the pressure on the inlet port is below a threshold value, and defining a second fluid passageway between the inlet and outlet ports for the flow of fuel through the valve assembly when the first valve member is preventing the flow of fuel through the first fluid passageway;

    an overflow chamber coupled between the outlet port of the valve assembly and the vent port of the vessel for collecting any fuel passing through the valve assembly; and

    a fill container defining a first aperture for receiving a fuel nozzle to fill the fuel tank with fuel, and a second aperture for coupling the fill container in fluid communication with the fuel tank to permit fuel to pass between the fill container and the fuel tank and to collect excess fuel within the fill container upon filling the fuel tank with fuel.
