One embodiment of the invention relates to an electronic fuel injection module including a throttle body including a throat extending between an inlet port and an outlet port and a fuel delivery injector too unit. The fuel delivery injector unit includes a cavity, a fuel inlet, a magnetic assembly, a pumping assembly, a spring, a valve seat, a valve, and an out valve. The fuel inlet receives fuel and directs fuel into the cavity. The magnetic assembly is within the cavity and includes a magnet, a pole, and a hollow sleeve. The pumping assembly includes a bobbin and piston. The bobbin is configured to move the pumping assembly. The piston is coupled to the bobbin. The valve seat is located at one end of the piston. The valve selectively allows fuel to flow into a pressure chamber. The out valve is configured to provide fuel to the throat.
