燃料ストレーナのエア抜き装置。 In the fuel system of a diesel engine, which consists of a route for supplying fuel from a fuel tank to an injection pump via a fuel strainer and a fuel supply pump, and a fuel return route between the discharge side of the fuel supply pump and the fuel tank, a fuel strainer is used. The upper part of the fuel supply pump and the suction side of the fuel supply pump are communicated through a check valve and an air bleed on/off valve that close when the fuel rises, and a fuel return on/off valve that communicates with the air bleed on/off valve is interposed in the fuel return path. An air bleed device for a fuel strainer in a diesel engine, characterized by:
