A remote fill system for an L-P gas cylinder providing a filler valve fitting, a vent valve fitting, and a service valve fitting, the fill system comprising a service box remotely located from the cylinder. The cylinder may be placed, for instance, in a remote location and permanently attached to a recreational vehicle. Then the service box may be placed adjacent a convenient exterior side panel of the vehicle. A filler valve, sight valve, regulator valve, manually-operated service valve, and electrically-operated visual sight gage all may preferably be disposed in the service box. The various valves, in the service box, are connected to their respective fittings on the cylinder by flexible hoses, and the visual sight gage is electrically connected to a volumetric indicating device on the cylinder. Since the flexible hoses might be ruptured or broken, excess flow valves or check valves disposed in the fittings on the cylinder are provided for the flexible hoses, each such valve being effective to prevent the outward flow of gas at least in hazardous volumes if its hose is broken.
