Fit all H-D with Delphi fuel injection. This fuel sharing system solves the age old problem of one of the brothers running out of gas. When on the road just click/remove your fuel line from the fuel tank and click-install the ´Fuel Sharing System´ in its place and start transferring fuel. Super simple and no tools required. Push the button on the hand unit and it will enable you to transfer fuel; at a rate of approx. 1 quart (almost a liter) per 20 seconds; with the engine running. Great for use at home as well; to gravity drain your fuel tank for maintenance / repair or winter stop. When your done; just remove the ´Fuel Sharing System´ and click-install your regular fuel hose back into the tank. Power flow: Connect between the check valve of the fuel tank and the fuel hose. When the bike is started the pressure builds up and fuel will flow; only when the button in the hand-unit is depressed. Drain flow: Alternatively the fuel sharing system will let you gravity-drain the fuel tank; without starting the bike; by not connecting the fuel hose and just depressing the pin in the fuel line adapter with the rubber ''fuel release tool''. The Fuel Tool includes a storage pouch for on the road transportation.
