過器。In a fuel filter installed downstream of a fuel pressure damper in a fuel supply pipe connecting the discharge side of a fuel pump and a fuel injection valve, a case having a fuel inlet vibrator on the lower side and a fuel outlet vibrator on the upper side is attached to the upper body. A fixed annular filter with a certain length in the vertical direction is installed to filter the fuel, and the outlet vibrator is extended from the upper body to the inside of this filter, and the base end of the outlet vibrator is connected to the upper body of the case. A damper chamber is formed between the inner upper surface and the case so as to form an air pocket when the case is filled with fuel, and the passage cross-sectional area of the outlet vibe is made smaller than that of the inlet vibe, and the inlet and outlet vibes are connected to each other. A fuel filter for an internal combustion engine with a fuel injection device, characterized in that the distance between the base ends of the damper chamber is greater than the distance between the liquid level of the damper chamber and the upper surface inside the upper body.
