The system includes a sealed vaporizer operationally parallel with the conventional carburetor system. The vaporizer includes a stabilized float valve for controlling fuel flow therethrough and various check valve arrangements and component arrangements which eliminate any possibility of lost fuel in case of collision or upset of a vehicle powered by an engine employing the vaporizer system.Field of SearchAutomatic water control; suction | |
