Fuel leak in Z32, coming from the rear. Don't want it to go up in flames

I have a 91 Z32 NA 2+2. Previous owner replaced all the fuel lines and clamps with the quick connector pressure ones and I checked all of them under the hood, they seem solid. No fuel smell under the hood either.

In the cabin the fuel smell is pretty bad but I can't tell if it's coming from the rear seats where the fuel sender is or just seeping inside. I can also smell it pretty well under the car near the rear driver's side tire.

I'm not super familiar with the fuel system in the Z32 but are these pictures fuel lines? I inspected visually for any kind of leak but didn't find anything.

Really want to track this down so all advice is appreciated.
