Not to mention highly flammable. Don't fool around with gas leaks!

Get it fixed.

I finally got around to fixing the leak. Simply tightening the clamp
did no good. I would still see a trace of fuel under the bottom of the
hose after driving for awhile. After removing the filler hose from the
tank end, I discovered light surface rust all around the hose fitting on
the tank - just under where the hose attaches. There was also a ring of
the oxide inside the removed hose as well. I believe the fuel was
seeping through this deposit, ever so slightly, but enough to smell up
the interior and the trunk. I steel wooled the oxide off the fitting
and used a dull knife to scrape it off the interior of the hose, then
reassembled. No more smell!
