A fuel system for a marine propulsion system includes a reservoir that defines a cavity in which first and second fuel pumps are disposed. The reservoir is mounted on the marine propulsion system at a location which causes the reservoir to be at least partially submerged within, and in thermal communication with, water in which the marine propulsion system is operated when a propulsor of the marine propulsion system is inactive. The first fuel pump is a lift pump which draws fuel from a fuel tank and pumps the fuel into the cavity of the reservoir. The second fuel pump is a high pressure pump which draws fuel from the cavity and pumps the fuel at a higher pressure to a fuel rail of an engine.

A fuel supply system for a marine engine provides an additional fuel chamber, associated with a fuel vapor separator, that receives fuel vapor from a vent of the fuel vapor separator. In order to prevent the flow of liquid fuel into and out of the additional fuel chamber, a valve is provided which is able to block the vent of the additional chamber. In addition, a sensor is provided to provide a signal that represents a condition in which liquid fuel within the additional fuel chamber exceeds a predetermined level.

A device is provided for allowing a conduit to extend through a wall while providing a seal around the conduit. The conduit extends through an opening formed in the wall and the conduit has a first end, a second end, and a central axis extending within the cavity of the conduit and along its length. First and second protrusions of the first end of the conduit are shaped to be received through first and second slots of the opening formed through the wall. A resilient seal member is attached to the first end of the conduit and is compressible by moving the conduit out of a first position relative to the opening in which the first and second protrusions are aligned with the first and second slots. By moving the conduit away from its first position, the resilient seal member is compressed to provide a liquid seal which prevents liquid from leaking through the opening formed through the wall.

A supporting structure for a fuel filter assembly provides a latch which is manually movable without the necessity of tooling into either a locking position or an unlocking position. By manually moving the latch, a collar of the fuel filter assembly can be freed to rotate about a supporting cover so that the reservoir can be removed. The assembly can also be manually removed from a support bracket without the use of tooling. The fuel filter assembly provides a resilient mounting system that isolates the fuel filter and its associated components from the vibrations that are inherent in an internal combustion engine.

An adjustment assembly for axially positioning the spool and associated centering spring within the bore of a valve body includes a cylindrical sleeve disposed around and connected to the cylindrical surface of the spool. The cylindrical sleeve includes radial surfaces that act to adjust the spring seats for the centering spring so that axial movement of the cylindrical sleeve results in axial movement of the spool and the spring seats for the centering spring.

A fuel pump is housed within the structure of a portable fuel tank. The inlet of the pump is located in the lower portion of the tank and an outlet of the pump is connectable in fluid communication with a flexible conduit. An opposite end of the flexible conduit is connectable in fluid communication with the fuel system of an outboard motor. A water sensor and a fuel level sensor can be provided in conjunction with the pump and attached to the pump in certain embodiments. A fuel pressure regulator is connected in fluid communication with the outlet of the pump and also located within the structure of the portable fuel tank.

A control valve for a pressurized fluid-operated system, such as a marine power steering system, includes a housing having an inlet and at least one outlet, with one or more work ports located therebetween. Pressurized fluid is supplied to the inlet, and a spool member is mounted within the housing for controlling the supply of pressurized fluid to a work-performing system, such as the extendible and retractable rod of a hydraulic cylinder assembly. The spool member includes structure for blocking the one or more work ports when the spool member is in its neutral position, when it is desired not to operate the system. This prevents the cylinder from being exposed to reservoir fluid when the spool member is in its neutral position.
