Abstract: A fuel supply device mounted on an automotive vehicle includes a fuel pump and a sub-tank containing the fuel pump therein. The sub-tank and the fuel pump are submerged in fuel contained in a fuel tank. Operation of the fuel pump is controlled in a switching manner thereby to supply the fuel contained in the fuel tank to an internal combustion engine.

To shield such noises, the fuel pump is disposed in the sub-tank that is made of a metallic material and grounded to a body of the vehicle. In this manner, the noises from the fuel pump are surely intercepted.

Abstract: A movable fuel valve lies within a housing at an end of a housing fuel passage. A fuel tube has a nozzle end inserted within a first end of the housing fuel passage while the movable valve element is situated at a second end of the housing fuel passage and controls fuel flow from the second end of the housing fuel passage. The nozzle end remains surrounded in fuel when the valve element is closed and sealed against the second end of the housing fuel passage. When the fuel pressure within the housing fuel passage is greater than a fuel pressure on the other side of the valve, the fuel flows from the housing fuel passage, through the part of the housing surrounding the valve, and into the reservoir. The movable valve element prevents fuel from flowing from the main-side of a fuel tank to the sub side of the tank.

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.

Abstract: In a fuel supply system, liquid fuel is supplied to a marine engine from a fuel tank (10). The fuel first passes through a water filter (14), a lift pump (18) and is temporarily deposited in a vapor separator (20) where vapors given off from the fuel are collected and vented. A high pressure pump (30) withdraws liquid fuel from the vapor separator (200 and delivers it under pressure to an engine injector system (36) via a fuel delivery line (34). The fuel pressure between the high pressure pump (30) and the engine injector system (36) is monitored to determine whether the engine injector system (36) is being presented with more fuel than is required for efficient engine operation. If more fuel than needed is being supplied by the high pressure pump (30), the unneeded fuel is returned to the vapor separator (20) through a bypass line (40).
