Abstract
A fuel handling system for an internal combustion engine having a vapor separator for receiving fuel from a remote tank and a pump for delivering the fuel under high pressure to a fuel injector of the engine while providing vapor separation. The separator has an inlet for receiving fuel from the tank, an outlet for enabling fuel to be removed and delivered to the engine, at least one return for enabling fuel not used by the engine to be returned to the separator, and a vent for removing fuel vapor from a gas dome above a pool of liquid fuel within the separator. The inlet has a valve controlled by a float in the reservoir for admitting fuel to maintain the level of liquid fuel in the separator. To retard foaming and excessive vaporization of liquid fuel in the separator, the separator has a perforate baffle between any return and the liquid fuel pool. To prevent any stream of returned fuel, vapor and/or air from impinging against the fuel pool, the baffle preferably has a plurality of through-openings which enable liquid fuel to pass through the baffle to the pool while deflecting any return stream away from the fuel pool. The baffle preferably extends outwardly to the separator si…
