Yamaha style marine 3 Meter Fuel Hose. This is the same hose that is included in all of our fuel kits. The Yamaha part number for this hose is 6YL-24306-64-00.
You will notice that this is a 6MM fuel hose, please do not substitute a larger fuel hose. A larger fuel hose will not work correctly due to the fact that you will not get as good of capillary action.
