• at least one fuel flow control valve located between the fuel chamber and both the low speed port and the high speed port to control the flow rate of fuel to the low speed port and the high speed port;
• and
• at least one passage communicating the fuel reservoir with both the low speed port and the high speed port and through which fuel in the fuel reservoir is supplied to the ports, said at least one passage also communicating the fuel reservoir with the fuel chamber, wherein said at least one fuel flow control valve is located between the fuel reservoir and both the high speed port and the low speed port, and between the fuel chamber and both the low speed port and the high speed port, and said at least one passage includes a portion extending between the fuel reservoir and the fuel chamber independently of said at least one fuel flow control valve.
