ABSTRACT:
A combustion engine system has a tank for volatile fuel with a flexible bag inside equipped with its own breather valve separate form the fill pipe for the tank. When the tank is filled, a muff around the full pipe seals the tank against exhaust of volatile vapors, and air from the bag is forced out the breather valve as it is displaced by the liquid fuel until a valve element on the bag shuts off the breather valve, whereby only pure air is vented to the atmosphere. As the tank empties during use, air returns through the breather valve to fill the bag and replace the space in the tank previously occupied by the liquid fuel, and incoming air may be dried. There is a vapor return for the automatic nozzle used to fill the tank with fuel from a stationary reservoir at the filling station and automatic means to prevent filling the tank until the nozzle is sealed in the fill pipe.
