bottomless tank on my 94 VFR750?

The smell went away and yes it is a non CA version.

 

Tore the bike down today, and it seems like I may have found the source of the gas smell. Took off the tank, flipped it over, and the insulation that's molded to the bottom of the tank was damp and had stain marks. Saw gas dribbling out (very little/very slowly) from where the fuel sending unit (that I installed a couple weeks ago due to the lo fuel light not working) connects to the tank. The O-ring is new as well, so I removed it, checked the o-ring, and put it back on. It really was maybe one or two drops a minute coming out from the bottom of the fuel sending unit base.

At least one of the bolts is stripped a little near the top of the bolt too. Anyone have any idea how to replace these? The bracket they are attached to seems welded to the bottom of the tank? Any ideas? Cannot tell for sure, but I think the bolts may be welded to the bracket as well, since they do not turn at all.

Right now, it is no longer leaking and the bolts are tight, but the bolts will have to be swapped if they have to come off again. This seems to be the issue, as I noticed I do not smell gas when the tank gets down to about half: which seems to be below the fuel sending unit base seal.

Did not see a canister on the bike at all, so now I know it's a non-CA version, BTW.
