A system for delivering propane from an outdoor liquid propane storage tank to a building structure is provided having a first pressure regulator mountable to an outdoor liquid propane storage tank, a metallic fuel line extending from the storage tank to the building structure, a second pressure regulator mountable to the building structure, and a union valve. The union valve mounted adjacent the second pressure regulator in the fluid flow path between the fuel line second end and the second regulator inlet, and having an ON and OFF position to enable the propane to be quickly turned off. The union valve including an integral dielectric member isolating the fuel line from the second fuel pressure regulator inlet, to provide a dielectric break between the building and the fuel line, without using a separate non electrically conductive fuel line section.
