Abstract
A system and method for controlling the release of fuel vapors and liquid fuel from a vehicle fuel tank is provided. The system includes a vent path leading from the dome of the fuel tank to a vapor capture device such that when the fuel tank cap is in place the vent path is opened when the pressure in the dome exceeds a predetermined value, when the cap is removed the vent path is opened irrespective of the pressure in the dome, and upon insertion of the fuel nozzle into the filler pipe the vent path is closed.
