A dual jet pump structure for a saddle type fuel tank is provided to suck fuel with high speed and low pressure fuel formed at each jet pump and to keep a reservoir cup full of fuel by installing two jet pumps parallel to a front end of a pressure regulator. A dual jet pump structure for a saddle type fuel tank including a main chamber and a sub-chamber comprises the followings: a pressure regulator(30) controlling pressure of an injection nozzle toward an engine; and a first jet pump(22) and a second jet pump(24) installed parallel adjacent to the pressure regulator in the same vertical plane. The first jet pump is connected to a suction hose reaching to the sub-chamber, to suck fuel in the sub-chamber, and the second jet pump is connected to a suction groove formed at a bottom surface of the fuel tank, to suck fuel in the bottom surface of the fuel tank. A separating wall(26) is installed between the first and the second jet pump.
