Brand new 2 piece CPC chrome plated brass quick disconnects for BMW R1150GS ADV bikes only ( just the 1/4" fittings for the crossover line on the ADV tank). These are made by the same company that supplies the OEM plastic units. The difference is ours are the high grade chrome plated brass version with stainless internals and fuel resistant Viton O-rings. We also include 2 fuel injection rated hose clamps and a spare Viton O-ring. These are the units BMW should have supplied in the first place. Don't be fooled by less expensive but cheaply made cast zinc parts that are being sold elsewhere. Due to the slightly larger size of the metal disconnects, the cross over line is more difficult to fish out from above the motor. For this reason we suggest using 2 of these 90 degree 1/4" fittings, one on each side of the tank. This way the crossover line stays put on top of the motor and the 90 degree elbows are simply disconnected and the tank lifts off. If you are purchasing our full 1150GS ADv kit or have one already then you will only need to order one of this set.
