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.
