Abstract: Systems and methods to vent a tank to enhance transporting asphalt when positioned in the tank may include connecting a vapor box to a tank. The vapor box may include one or more vents apertures and a valve associated with the one or more vent apertures and positioned to provide fluid flow between the interior of the vapor box and the exterior. The systems and methods may also include communication via a selector with the valve to cause the valve to switch between an open condition and a closed condition. The selector may be located remotely from the valve, and the systems and methods may also include communication with an indicator via one or more of the valve or the selector to provide an indication of one or more of the valve in the open condition or the valve in the closed condition.
