Abstract
Several embodiments of outboard motor fuel feed systems wherein a position responsive valve is interposed between a remotely positioned fuel tank and the engine charge former for precluding the inadvertant flow of fuel to the charge former when the outboard motor is tilted up. In each embodiment, the valve is a gravity responsive valve and in another embodiment a pressure responsive valve member is provided for ensuring fuel flow when the outboard motor is again tilted down to its normal running position.
