ABSTRACT:
An integrated fuel management system and method for controlling the fuel storage and delivery in a vehicle. The fuel management system includes a fuel storage tank for storing fuel in a vehicle, a vapor collection canister located within the fuel storage tank, a vent actuator coupled to the vapor collection canister for venting gas from the canister during a vent operation, and a purge actuator coupled to the canister for purging fuel vapor from the canister during a purge operation. A variable speed fuel pump is disposed within the fuel storage tank for delivering fuel to a fuel delivery line for an engine. The fuel management system has a controller provided in a module disposed in communication with the fuel for controlling the amount of fuel pumped with the variable speed fuel pump to deliver fuel to the fuel delivery line and further control the purge and vent actuators.
