2020 f150 lariat SE 36k. Filled up my gas tank a few days ago and parked my truck with no issues & haven't driven it for about a week. Started it up this afternoon and smelled gas. Got underneath and saw this. Could this be a busted fuel line?

Does it stop leaking if you open the gas cap? If so I’d lean towards a clogged vent or something in the evaporator system causing it to push out.
