Abstract
An outboard motor fuel vapor separator-venting system that vents fuel vapor from a fuel vapor separator through a vapor relief valve. The vapor relief valve is located in a high position on the outboard motor to ensure that liquid fuel does not reach the vapor relief valve. The vapor relief valve allows vapor to gradually be delivered from the vapor separator to an air induction system depending on the amount of air entering the air induction system and/or engine speed. The vapor relief valve does not allow fuel vapor to vent from the fuel vapor separator to the air induction system when the engine is not operating.
