Fuel supply device for fuel returnless system

摘要

A fuel supply device for a fuel returnless system is disposed in a fuel tank and includes: a fuel pump that draws, pressurizes, and discharges fuel in the fuel tank; a pressure regulating valve that regulates the pressure of the pressurized fuel and drains a surplus of the pressurized fuel into the fuel tank; an intake filter that removes foreign matters contained in fuel drawn into the fuel pump; and a pressurized fuel return passage through which a part of the pressurized fuel is returned to a fuel intake passage extending from an interior of the intake filter to a pump intake port of the fuel pump.
