Default Fuel smell at fill up help please

Hello,
2011 base coupe
fuel smell after fueling and a short time rough running too led me searching.
no check engine or any codes
I replaced purge valve at right front valve cover just cause easy
I looked at right rear evap area for anything odd and I see a vac or fuel line rubber with a tee that is open on the top.
see pics and please advise if normal or did it come off or break.
top of tee not attached to anything



Spoiler

The most common cause of a raw fuel smell on C6s is the top of the fuel pump assembly cracks and leaks fumes. You'll have to drop the fuel tank to replace but but with a good bore scope you can probably get up there to look.
