Brand new 4 piece 5/16" CPC chrome plated brass quick disconnects for BMW R850/1100/1150(EXCEPT R1150GS ADV)& R1200C and K1200RS/LT/GT fuel lines. These are made by the same company that supplies the OEM plastic units. Replaces BMW part #s 13317659120 and 13317659119. The difference is ours are the high grade chrome plated brass version with stainless internals and fuel resistant Viton O-rings. We also include 4 fuel injection rated hose clamps and a spare set of Viton O-rings. 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. The set includes enough quick disconnects and clamps to change over both fuel lines on your bike. A great upgrade for older Oilheads and K-bikes that did not come with quick disconnects originally.
