A fuel system has a fuel tank with a wall and a fuel delivery outlet through which fuel is delivered to the engine. The fuel tank has a fuel suction tube extending from the fuel delivery outlet into the fuel tank. Fuel is drawn to the engine from the fuel tank through the suction tube and the fuel delivery outlet. The fuel tank has a fuel cooling return inlet through which unused fuel warmed by the engine may be returned to the fuel tank and cooled. A fuel cooling conduit is coupled to the fuel cooling return inlet. The fuel cooling conduit has at least one fuel dispersing outlet through which fuel is dispersed onto the fuel tank wall to cool the fuel. A fuel warming return inlet is provided through which unused fuel warmed by the engine may be directed to flow adjacent the suction tube to heat the fuel being delivered through the suction tube to the engine. A shroud may also be provided to blend returning warm fuel with cooler fuel from the fuel tank that is flowing toward the suction tube.
