Abstract
A fuel supply system for an internal combustion engine comprises first and second fuel reservoirs connected in fluid communication with each other. The first fuel reservoir is a fuel vapor separator which has a vent conduit connected in fluid communication with a second fuel reservoir. Under normal operation, fuel vapor flows from the fuel vapor separator and into the second fuel reservoir for eventual discharge to the atmosphere. Any liquid fuel caused to flow out of the vent conduit of the fuel vapor separator is contained within the second fuel reservoir and prevented from being discharged into the cavity under the cowl of an outboard motor and eventually into a body of water in which the marine system is operated.
