Fuel line help?

So I was loading my 250 bruin in my horse trailer…come back a few minutes later and smell gas! Some how fuel line got unhooked? For the life of me I can not see where to goes back in though!!! I feel so blind. It’s only letting me upload one pic at a time from my phone but hopefully someone can point it out for me. I’m usually not this dumb about this stuff but I think my brain is so fried from moving 8 hours.
