Abstract: A stationary fuel storage system that includes a stationary fuel tank that defines a tank volume adapted to store a quantity of fuel. An evaporative emission device is disposed outside of the tank volume and defines a device volume that is in fluid communication with the atmosphere. A mass of fuel vapor adsorbing material is disposed within the device volume and a vent conduit provides fluid communication between the fuel tank and the evaporative emission device.

Abstract: A fuel vapor control system that is adapted for use with internal combustion engines includes a fuel tank, an evaporative emission control device containing activated carbon and including a first orifice that fluidly communicates with the fuel tank via a vent line. A second orifice in the control device is open to the atmosphere. A purge tube is between a filter element and a venturi section of the engine and fluidly communicates with a third orifice in the control device via a vapor line. Fuel vapors are absorbed by the activated carbon when the engine is not running, and the carbon releases the fuel vapors to the engine via the purge tube when the engine is running.
