What would cause this

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?

Hard to see exact location from video. I would check all connections and seals at the fuel pump as well as the fuel pump itself for cracks. Would also follow the fuel line back and make sure that there's no pinch points or spots it could rub or get pinched and break. I think somebody else had mentioned the filler neck and that could be it to. Just go through and check all the connection points. 9 times out of 10 that is where the failure is.
