Patent ID: 8371271

Claim:
An outboard marine engine vapor vent control apparatus, comprising: a body configured for detachable connection to a fuel connector upstream of said body, said body having a fuel inlet configured in fluid communication with a fuel reservoir downstream of said body, said body and having a one-way valve, said fuel inlet being configured for operable attachment to a fuel pin of the fuel connector, wherein, when attached to the fuel pin said one-way valve automatically moves to an open position to allow liquid fuel to flow through said one-way valve to the fuel reservoir and when detached from the fuel pin said one-way valve automatically moves to a closed position to prevent the flow of liquid fuel out of said fuel inlet; a vapor vent passage extending through said body, said vapor vent passage configured to bring the liquid fuel reservoir on one side of said vapor vent passage in fluid communication with an air intake of the engine on an opposite side of said vapor vent passage; a vent pin passage extending from said vapor vent passage outwardly from said body; and a vent pin disposed in said vent pin passage, said vent pin being automatically movable between a first position upon attaching the fuel connector to said fuel inlet and a second position upon detaching the fuel connector from said fuel inlet, wherein, when in said first position said vapor vent passage is open to fuel vapor flow from the liquid fuel reservoir through said vapor vent passage to the air intake and when in said second position said vapor vent passage is closed to fuel vapor flow from the liquid fuel reservoir to the air intake.
