A marine propulsion system includes a two cycle water cooled crankcase compression internal combustion engine (52) including a vapor separator (33), a remote fuel tank (60), and a fuel pump (62) in the tank for delivering fuel to the engine in response to crankcase pulse pressure. A combination conduit (64) between the fuel tank and the engine includes a first passage (66) communicating crankcase pulse pressure from the engine to the fuel pump in the tank, a second passage (70) supplying fuel from the pump in the tank to the engine, a third passage (74) returing fuel vapor from the vapor separator at the engine back to the tank, a fourth passage (78) supplying cooling water from the engine towards the tank, and a fifth passage (82) returning water from the fourth passage back to the engine.
