I have a small hose on my 2007 1000rr filler cap from what I can see that leads to the very bottom of my fuel tank and is welded to the bottom. I noticed it started rusting and there was some gas in my filler cap that wasn't draining through it/ a.k.a backed up, proabobly why it started rusting. Is this the breather hose or drain hose and is it suppose to get backed up at all or drain right through fast? Help! Solutions? Thanks in advanced.
P.S. In the pic the small black hole is what I'm refering to at 12 o'clock.
