Abstract: A housing has an inner passage to communicate with both a fuel passage, which is to conduct fuel from a fuel pump, and a return passage, which is to return fuel a fuel tank. A valve body is movable in the housing to change a minimum flow passage cross-sectional area of the inner passage. A spring is connected to the valve body and changes its biasing load in correspondence with a fuel temperature to move the valve body. The spring moves the valve body such that the minimum flow passage cross-sectional area, when the fuel temperature is equal to or higher than a predetermined vapor generation temperature, is larger than the minimum flow passage cross-sectional area when the fuel temperature is lower than the vapor generation temperature.

Abstract: In a fuel tank, a pressure regulator is placed at an outside of a sub-tank and regulates a pressure of fuel of a pressure-regulation path, which is discharged from a fuel pump and is fed toward an outside of the fuel tank.

The fuel recovery passage portion is inserted from the outside of the sub-tank into the inside of the sub-tank through the opening while a gap is formed between the fuel recovery passage portion and the opening, so that the fuel recovery passage portion has an excess fuel outlet that discharges the excess fuel at a location that is on an inner side of the opening where an inside of the sub-tank is placed.
