An air/fuel handling system for a small fuel injected engine with a preferably extruded body having an air tuning chamber, a fuel pump chamber and a fuel rail chamber therein for supplying fuel to one or more fuel injectors. A preferably separate fuel metering and throttle body is mounted on the chamber body. Air is supplied to an intake passage of the throttle assembly to the air chamber which has ram tubes for supplying combustion air to the intake manifold of the engine. Fuel from a remote gasoline tank is supplied through a metering valve assembly to the inlet of an electric fuel pump mounted in the pump chamber which supplies high pressure fuel to the fuel rail and injectors and thus to the engine. Fuel vapor in the metering chamber is separated from liquid fuel and supplied to the air intake chamber when the engine is operating.
