Keep in mind that the outdoor smell has a LOT of space to dissipate 
into, while the interior is confined. That alone could account for 
the difference in smell intensity.

It could be a very small leak at one end or the other, just outside 
the interior. A leak there could seep down the hose and onto the pipe 
leading into the interior and follow that pipe past the grommet and 
into the tunnel.

Since it leaks with the tank low and the engine off, we know it's not 
the overflow hose or the tank seam, but we also know it's not 
dependent on FI pressure. You may have to get where you can reach in 
and feel for wetness at the 4 places where those pipes feed into the 
interior.

Dave's talking about the horizontal seam where the upper and lower 
half of the tank are welded together. That's inside the trunk. You 
might want to do a visual inspection under the trunk liner sometime 
after you've topped up the tank. Just look for wetness at any of the 
upper hose connections. Trunk leaks tend to smell in the interior 
also.
