Abstract
A vehicle fuel system has an electronic control module received within a fuel tank to send data to and receive data from the electronic control unit (ECU) for the vehicle engine and other vehicle control systems, to provide an electronic control of the vehicle fuel system and to receive signals from one or more sensors mounted within the fuel tank which provide information about the operation of the fuel system. The fuel system integrates a plurality of components into the vehicle fuel tank to reduce the number of openings through the vehicle fuel tank and the number of external connections which must be made in assembly of the fuel system into a vehicle. By disposing a fuel vapor canister within the fuel tank, each vapor vent valve within the fuel tank can communicate completely within the tank with the vapor canister with a single outlet extending from the fuel tank to communicate fuel vapor from the canister with an intake manifold of the engine. Desirably, this outlet may extend through the same opening in the fuel tank through which the fuel pump, vapor canister, electronic control module and other components of the vehicle fuel system are inserted into the fuel tank. Notably,…
