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 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.

Fuel delivery system for a marine propulsion device

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.

Fuel reservoir mounted to a driveshaft housing of an outboard motor

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.
