Motor fuel dispensing units at multi-fuel refueling stations must be installed on raised concrete foundations. For dispensers located at multiple fuel refueling stations where the propane dispensing cabinet is located at a fueling island, most local jurisdictional authorities require the installation of a breakaway coupling, sometimes called a “foot valve.” Courtesy Clean Fueling Technologies Figure 2.
