New O-ring and hose clamp set for changing the fuel filter on all R850/1100/1150 and R1200C bikes. This kit includes the O-rings for the fuel pump plate and fuel filler cap, and 2 Viton O-rings for the fuel line quick disconnects as well as 2 fuel injection style hose clamps for the fuel line, 2 corbin type clamps for the vent lines and also 2 Viton o-rings for the fuel line quick disconnects (if your bike has them). Replace those hard to deal with OEM BMW Oetiker style clamps with reuseable, easy to handle clamps. You will need to replace the O-rings when replacing your fuel filter (fuel expands the old o-rings and makes them very difficult to reuse). New these parts are over $20 at the dealer, save here!
