In a fuel injection apparatus in which a pressure regulator is attached to a vapor separator, in order to make the vapor separator compact, to improve corrosion resistance of the pressure regulator and to maintain a stable pressure regulating operation for a long time period, a vapor separator is constituted by a chamber and a cover, a pressure regulator is arranged within a recess portion of the cover and above a fixed fuel liquid surface, the longitudinal axis of the pressure regulator is arranged in a state of being approximately parallel to the fuel liquid surface, a pressure fuel inflow passage is formed in the cover and is formed so as to be branched from a fuel discharge passage formed in the cover, and a vent hole of a spring chamber is open at a lower position in the gravitational direction.
