A two-stage vent valve is incorporated into a vehicle fuel distribution system. The vent valve is mounted to the top of a fuel tank of a motor vehicle in a vertically orientated position, so that a fluid inlet is in communication with the interior open air volume of the fuel tank, and an outlet is in communication with the exterior of the tank. The vent valve utilizes a two-stage valve mechanism to allow vapor to escape from the fuel tank, while preventing the leakage of liquid fuel during such operating conditions where the vehicle has tilted due to a small downgrade, sloshing of fuel in a full or near-full tank, or the event of a roll-over.
