Abstract
A fuel system for a vehicle having a generator includes a fuel reservoir which taps into the main fuel tank. A solenoid pump pumps fuel from the main fuel tank to the reservoir which in turn feeds fuel to the generator. A fuel shut-off valve is provided in the reservoir to prevent overfilling of the reservoir without the need for a fuel level sensor or pump control electronics. The valve is operable to close upon the fuel level reaching the closing height of the valve. Closing of the valve causes the pump to idle, thus stopping the flow of fuel into the reservoir. Fuel is still allowed to flow from the reservoir to the generator, thus allowing uninterrupted running of the generator. When the fuel level in the reservoir dips below the closing height of the valve, the valve opens and the pump again starts pumping fuel into the reservoir.
