It could be leaking on to somethin hot and evaporating which is why
you smell it so strongly, or it could be the charcoal cannister full of
gas if you have always topped it off too much when you get gas over the
years. I have a van at work that does that because the guy that drove it
for years before me used to keep clicking ght pump until gas came all
the way up the neck.

If you don't see any external leaks it could be one or more leaky
injectors.

I had that issue once.  Turned out to be a bad coil.

yer canaster may not have the vacuume hose on it, the little elbow in rubber
expands, falls loose, no replacements for it from anybody yet.

I've had both a leaky fuel injector and a rotted line from the vapor
recovery canister give me that problem.  Look at the tops of the injectors,
see if you can find one that is significantly dirtier than the rest and
looks to be damp on the top.  Also give your lines on the vapor recovery
canister the wiggle test to see it they are cracked and leaking.
