ABSTRACT:
A fuel supply system for an engine powering an outboard motor is disclosed. The fuel supply system includes a pump for supplying fuel from a tank to a vapor separator. Another pump delivers fuel from the vapor separator to at least one charge former for supplying fuel to the combustion chamber(s) of the engine. The fuel supply system includes a mechanism for reducing the transmission of vapor to the pump which delivers fuel to the charge former(s). In one embodiment, this mechanism is a vapor relief line extending to a point outside of a cowling of the motor in which the engine is positioned. In another embodiment, the mechanism is a pump control, and in yet another, the mechanism is a vapor separator cooling system.
