WTF is going on here?!?!?!?!

Guys, as i was changing my oil today i was about to close the hood when I noticed what looked like a fuel line just hanging around the engine bay. I thought to myself "this cant be, it cant be a fuel line because my car runs and it has gas". Then it donned on me that my car has been "bogging down" when i smash the gas sooooooo this might actually be a fuel line. Long story short it is. I have one line going from the gas tank to the fuel pump to the carb. Guys, how is this possible??? Any ideas on where this line hooks up to? As far as i can tell without dropping the gas tank its still connected to the gas tank but its dry and just hanging around. Im gonna try and enclose some pics but any help would be greatly appreciated...
