A small cylindrical vessel connected to a gas fine in the oil field to provide an even flow of gas to an engine and to trap liquids that may have condensed in the gas line. The volume tank is usually located a few feet away from the gas engine fuel line takeoff. One reason for volume tank, besides its, being a small catch vessel for water and drip gasoline (q.v.), Is that gas from the lease is piped to each gas engine through a small pipe, often one inch, and as the engine intakes gas the small pipe would not provide a steady and continuous enough supply.
