Fresh fuel smell in cabin!

[Thatasianone]

My fuel filler neck is super loose inside my car. I don't know if it's supposed to be loose or not to be honest. I live in Oregon so I rarely see my fillerneck/gascap but is it supposed to be loose? When I say loose, I mean if I put my hand on the cap, and shook it, it doesn't even feel like it's really attached to anything, but it does jump back to the spot where it was.

I went under the car and reached for where the filler neck and hose connect and there is NO clamp. Can anyone else confirm that there is no clamp? (No reason there shouldn't be)

I'm still getting around 26-27 MPG with it, but the gas smell lingers randomly. (Can't tell if I take a right, left, or accelerate when it smells, it's completely random) And the smell is ONLY inside the cabin. I don't smell it outside, in the engine bay, or even burning on the tranny when I'm driving.

It's a 95' Zenki.

Pictures would be nice! Thanks.
