<p>A pipe with a plurality of gas outlet apertures is inserted inside a fill pipe of a liquid storage tank. The fill pipe has an outlet normally covered by the tank contents. The gas pipe conveys the gaseous contents of the fill pipe to a separate outlet as refilling liquid is introduced into the fill pipe. This allows the gas inside the fill pipe to be separately vented from the fill pipe without disturbing the liquid contents of the tank.</p> |
