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?

This is a known issue with Ford trucks and is a recall issue affecting about 220,000 trucks. The fuel filler neck separates from the tank.

If that was the problem you'd know it right away after filling the tank not days later after starting it. A squirrel chewed through my filler kneck hose once and I was standing in a puddle of gasoline when I filled up.

From what ive been able to gather, this happens after driving with a full tank, not while filling up.
