SOLUTION: This device includes: a cover member blocking a fuel tank bottom opening; a pump holder retaining a fuel pump together with the cover member; a filter holding part holding a filter; a chamber formed of a lower part of the pump holder, an inside of the filter holding part, and the cover member; and a pressure regulating valve regulating the pressure of fuel delivered from a fuel pump. A return opening is formed on the upper surface of the filter holding part, a tip is installed isolated from the return opening for delivering return fuel from the pressure regulating valve toward the return opening, and return piping is installed to be directed to the return opening.
