ABSTRACT:
A vented fuel system for a vehicle includes a plurality of fuel storage tanks and a fuel sump tank with at least one fuel storage tank positioned on each side of the vehicle. The sump tank is positioned on the vehicle between the fuel storage tanks and at a lower elevation than the fuel storage tanks. Each of the fuel storage tanks is connected by a fuel line to the sump tank and all of the fuel storage tanks are interconnected by air transfer lines. One of the fuel storage tanks on each side of the vehicle is provided with a filler spout and a vented fuel cap assembly for closing the filler spout. All of the fuel tanks can be filled from either side of the vehicle, and during refueling, air is expelled from the closed vented fuel cap assemblies and the open filler spout. The plurality of air transfer lines prevent air entrapment in any of the tanks by transferring air between the tanks and subsequent venting of the air through either or both vented fuel cap assemblies. Fuel is gravity fed from the fuel storage tanks to the fuel sump tank.
