Abstract: In at least some implementations, a fuel supply module includes a reservoir and a fuel pump carried by the reservoir. The reservoir may include a body and a lid that define an internal volume to contain a supply of fuel, and the reservoir may include an inlet through which fuel enters the internal volume and an outlet from which fuel is discharged from the fuel supply module. The fuel pump is carried by the reservoir and has a first inlet communicating with the internal volume to take fuel into the fuel pump from the internal volume and a second inlet spaced above the first inlet relative to the direction of the force of gravity to take fluid or vapors into the fuel pump from the internal volume. The fuel pump includes an outlet from which fluid is discharged for delivery to an engine through the reservoir outlet.

Abstract: A marine outboard engine includes an internal combustion engine including at least one fuel injector; a fuel vapor separator including: a separator body, a fuel reservoir defined by the separator body, and a first fuel pump fluidly connected between the fuel reservoir and the fuel injector; a fuel tank; and a second fuel pump fluidly connected between the fuel tank and the fuel vapor separator. The fuel vapor separator includes a heat exchanger disposed in the separator body. The heat exchanger includes at least one fuel channel defined by the heat exchanger body, the at least one fuel channel including: an inlet adapted for receiving fuel from the engine, and an outlet fluidly communicating with the fuel reservoir; and at least one coolant channel defined by the heat exchanger body, the at least one fuel channel and the at least one coolant channel being in thermal communication.

Abstract: In at least some implementations, a liquid and vapor separator includes a body and a cover, a fuel inlet, a fuel outlet and a vent passage. A fuel pump has an inlet in communication with the interior volume and an outlet in communication with the fuel outlet. A fuel pressure regulator has an inlet in communication with the fuel pump outlet, an outlet in communication with the interior volume and a valve between the fuel pressure regulator inlet and the fuel pressure regulator outlet. The fuel pressure regulator is carried by the cover and the cover defines at least part of a fuel passage between the fuel pump outlet and the fuel outlet. An inlet valve is received within the interior volume and associated with the fuel inlet. A wall at least partially separates the area of the fuel pump from the area of the inlet valve.

Abstract: In at least some implementations, a fuel vapor separator for an internal combustion engine includes a main body at least partially defining a chamber for holding fuel, a lid carried by the main body to close the chamber and at least partially define a vapor chamber above a level of fuel in the chamber, and a thermoelectric heat exchanger coupled to the main body. In at least some implementations, the main body is a thermally conductive polymeric material that is resistant to degradation or dimensional changes, and in some implementations, the main body may be formed from a metal.
