PROBLEM TO BE SOLVED: To efficiently discharge air or vapor through an injector by arranging a fuel inflow restricting means in a fuel delivery pipe so as to restrict the inflow of starting time fuel to a single injector among plural injectors at the starting time. SOLUTION: A projecting part 50 and a hole part 52 are arranged in an upper part of an injector 6a, and its hole part 52 secures a minimum fuel flow rate necessary for starting to the injector 6a. Fuel supply is continued from a fuel supply port 33a, and the fuel supply to the injector 6a is performed only from a hole part 52 until a fuel surface reaches F1 . The fuel supply to the injector 6a is transitionally restricted, and vapor is gathered to an upper part of a fuel delivery pipe 36, and is collectively discharged in the VP direction from the injector 6a through an opening part 54. Therefore, in the case of high temperature starting time of an engine or the like, air or vapor accumulated in the delivery pipe is discharged through a specific injector.
