ABSTRACT:
Several embodiments of fuel supply systems for outboard motors and particularly those embodying fuel injection systems and remotely positioned fuel tanks. In each embodiment, a device is incorporated in the power head of the outboard motor for maintaining a uniform pressure of fuel delivery to the fuel injection nozzles by recycling a portion of the fuel back into the fuel system and within the power head. In some embodiments, the fuel is recycled directly into the fuel line before the fuel pump. In others, the fuel is recycled to either a delivery tank or an accumulator chamber.
