ABSTRACT:
A fuel injection adapter for a vehicle having a carburetor includes a fuel chamber coupled to the fuel pump of the vehicle, an operating lever adapted for coupling to the throttle lever of the vehicle and a pair of nozzles positioned in the throat of the carburetor for delivering fuel directly thereto. The nozzles are connected to fuel metering jets mounted in a wall of the chamber and corresponding fuel control needles are movable in and out of the jets to control fuel flow by means of a needle plate that is driven from the operating lever. The adapter can be mounted directly to the carburetor. A heater is positioned in the chamber for heating the fuel for cold weather starting. A shutoff valve is connected in the inlet fuel line and stops fuel flow into the chamber when the operating lever is in a position corresponding to a throttle wide open condition.
