I just had my busa painted and when I started to put the tank on, I connected to two fuel lines to the pump etc. and started to bolt the back of the tank on when I noticed two hoses hanging from the rear of the tank next to where the tank bolts to the frame???? are these breather hoses???? there is a small one and a large one. I am really confused since I can't find ANYTHING they connect to? If this helps my busa is a 99.........any help WILL BE GREATLY APPRECIATED!!!!!:wtf

Those are vent lines for your tank. They should already be connected to the underside of your tank. Just snake them through your wiring and let them hang out of the way. If you want to do it right get a hose routing diagram from the Busa service/shop manual.

Yep, just leave them open towards the ground, not hanging with the end over your swingarm or something. One of them is for tank overflow, so if some fuel sloshes out onto your swingarm or something it might get messy.
