Summary:PROBLEM TO BE SOLVED: To effectively suppress deterioration of high temperature restartability of an engine by suppressing production of air pocket in a fuel inlet chamber. SOLUTION: This device is provided with a fuel pump 15, a fuel filter 20, a housing 30 storing the same, a fuel delivery flow passage 12 introducing fuel to the fuel inlet chamber 34 via a check valve 13, a fuel pipe 45 and a pressure regulator 40. A branch flow passage 50 from a downstream of the check valve 13 is formed and is communicated to a section where air is easily trapped in the fuel inlet chamber 34. The lid 32 is arranged aslant and the pressure regulator 40 is arranged at a slant uppermost part. Fuel delivered from the branch flow passage 50 pushes air trapped in the fuel inlet chamber 34, and air collected at the slant uppermost part is released to outside of the fuel inlet chamber 34 together with surplus pressure by a pressure regulator 40.
