Question: I am working on a project with an engineering company that is building a gasoline truck loading terminal in Trinidad. The engineer says the trucks are 9,000-gallon capacity and are British Heil Trailer trucks. Do you know what type of coupler I need to connect my company’s loading arms to this type of truck? Chris
Answer: The British use the same API (American Petroleum Institute) bottom loading valve size as we do under DOT 406. This is in accordance with API RP1004 for total interchangeability with all loading valves used for petroleum liquids.
