Hi, I bought a brand new 2007 Yamaha FZ6, and it only leaks gas out of what appears like a pressure relief hose when I park it at work. In my garage it's fine, and currently it's half-full, yet still leaks. Any advice/reasoning behind why it happens when I park it outside, at work, only? It's in the shade, so it's not getting too much direct sunlight, but could it be that the pressure is building up and not escaping in time, and is instead forcing the gas out to relieve the pressure?

Any info is appreciated. Thanks!
