[s-cars] UrS fuel smell around tank

Q here for a friend thar.  

'95.5 sedan mit 150k reeks of gas inside car and outside, mostly after
fill up then dissipates mostly.  It's *definitely neither*underhood nor
not the lines down the pass side sill.  Definitely not those.  It's not
(seemingly) on top of the fuel pump basket.  

But the tank is wet coming down from the top, over the tank seam, and
down the bottom.  First glance to me thought tank seam but it at least
appears to be coming from above there.  

Any BTDT's on this?  It's hard to tell cause everything right there is
wet due to...

address the asphyxiator that now ferries his 3 week old girly...
