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 is coupled to the vapor collection canister for purging fuel vapor from the vapor collection 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 controlling the purge and vent actuators.

The invention claimed is: 1. A method of controlling a fuel storage and delivery system in a vehicle, said method comprising the steps of: sensing a condition indicative of a vehicle collision; and preventing the flow of fuel from the fuel storage and delivery system in response to detecting the vehicle collision condition includes blocking a fuel fill passage in response to sensing the condition indicative of a vehicle collision. 2. The method of claim 1 additionally comprising shutting down a vehicle fuel pump in response to sensing the condition indicative of a vehicle collision. 3. The method of claim 1 wherein the step of blocking a fuel fill passage in response to sensing the condition indicative of a vehicle collision is achieved by an electromechanical valve. 4. The method of claim 2 wherein the step of blocking a fuel fill passage in response to sensing the condition indicative of a vehicle collision is achieved by an electromechanical valve. 5. The method of claim 3 wherein the electromechanical valve is disposed within a fuel fill tube in communication with the fuel storage and delivery system. 6. The method of claim 4 wherein the electromechanical valve is disposed within a fuel fill tube in communication with the fuel storage and delivery system.
