Fuel connector O-rings x 2 used on fuel injected models. These O-rings are manufactured from Viton.
While ethanol mixed with petrol/gasoline is known to lower engine / tailpipe emissions, these blended fuels increased permeation through plastic and rubber. Viton has excellent chemical resistance and helps resist these problems. When removing a fuel connector, make sure the clip is released and while separating keeping square at all times until fully apart.
Fits T595, T509, 955 Daytona, 955 Speed Triple, TT600, Speed Four, Sprint 995 ST, Sprint 995 RS, Tiger 900 (injected) and Tiger 955
