Abstract: A carburetor fuel level management system includes a fuel level sensor mounted in the float bowl of the carburetor for monitoring actual fuel level and providing a signal indicative of the fuel level. The sensor may be used for data acquisition and/or to provide feedback to a controller which maintains fuel level at or near a preferred level by varying fuel flow rate into the float bowl in response to an indication from the sensor that the actual fuel level differs from the preferred fuel level. Fuel flow rate may be controlled by selectively bypassing a fuel pressure regulator in the carburetor inlet line or by varying voltage to an electric fuel pump, among other methods.

Abstract: An adjustable booster pump and controller is provided for controlling the amount of fuel delivered to an engine. The adjustable booster pump and controller utilize the engine's original fuel input system and may be used to increase the flow of fuel to the engine as a function of fuel demand. Various inputs may be inputted in the controller to determine under what conditions more fuel is needed. These inputs may be time, engine revolutions per minute, vehicle speed, manifold intake pressure, and others. The user may then selectively determine when more fuel is needed and may adjust the controller to increase the output of the booster pump to increase the fuel flow to the engine.
