*** Our Vented cap WILL LEAK. The cap is vented by machining a groove into the threads and below the gasket allowing the gasket to be bypassed. Tanks that are not stationary (Like in the back of a truck) will leak fuel as is sloshes back and forth.   We recommend using a NON Vented cap in all situations and utilize a vent port on the tank itself.
