This is a quick, clean and safe way to transfer fuel from your BMW R 1200 GS to another motorcycle or container. A permanent check valve is installed in the main fuel line that keeps a tight seal until you need to use it. The kit includes a matching receiver valve and 4' (1.2 meters) of fuel line to reach a gas can on the ground or the fuel tank of another motorcycle. Fuel is transferred using the fuel pump on your motorcycle -- no more breathing gas fumes to create a siphon. This kit is great for emergency situations on the trail or emptying a gas tank for winter storage. It's also extremely useful for servicing the bike, as you now have a dry-break to remove the gas tank.
