Vapor hose from the gas tank?

That hose should be normal =)

Yup, normal overflow hose from inside the filler door. Looks too long. Just trim it back.

I can't tell based on the pic, but there's likely a tab on the back/inside of the quarter panel area that the hose is supposed to be snapped under (flexible 'clamp'). Might want to see if there's one there and just tuck that hose back under it (which will take up the slack that's causing it to hang so low.)
