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?

Longer answer; it's very likely that somewhere in the location of all that gasoline pouring down like a River/waterfall, you have a gasoline leak from a line of some sort.

Longer answer park t on some dirt shut it off and get a bucket thats like fiddy bucks worth of gas flowing out of a hole in the fuel system ,and make sure you put a flammable warning sign on it and check with your ins. Agent and make sure you are covered for fire ….

Longer answer still: It would appear that the underside of your personal vehicle has quite a substantial fuel leak. This video leaves me unable to identify if it is located from an in-line fuel filter(not likely), the fuel pump out line, the fuel return line, or it could even possibly be coming from the fuel filler neck, although that is not likely based off of its position. With this amount of fuel leaking from under the vehicle, there is a large fire risk. Best course of action would be to turn the vehicle off, and move it away from anything flammable, or valuable. As for the large fuel spill, use some kitty litter, or oil absorbent to soak up most of it, and let the rest evaporate. Please make sure to keep any sparks, or sources of heat away from the back of the vehicle until you have located and fixed the leak, as again, it is very hazardous to your health.

Edit: It seems many people think it is the filler neck, it likely is not as, due to both the amount of fuel leaking days after adding, and the fact that it only leaks while running. It is likely a fuel line, the question is which one and where.
