strong gas smell under the hood

strong gas smell under the hood
Started driving today with the windows down (as usual) and immediately started getting this smell of gasoline coming into the cab. Poking around under the hood, the smell got a lot stronger.
Questions
1. Any ideas as to where gas leaks typically begin on a 3.0 (94 4-runner)? I'm trying to narrow things down here.
2. Should I be particularly concerned about driving the runner to a shop with the smell being as strong as it is?
I hate dealing with the fuel system.
Thanks folks...

update... o.k. now what?
I took the truck out around the block a couple of times to get her warmed up. I noticed immediately that there was no smell of gas this time. After driving around, I put her in park and opened the hood - still no smell. The first time I smelled fuel a 2 days ago, I had literally started her one morning to go to work and as I pulled away from the driveway I noticed the smell immediately... this is first time I have started it since and no smell.
Could this be a canister problem or could we still be looking at an injector/O-ring problem?
P.S. thanks for the earlier replies guys...

Try jumping the terminals in your dignostics port to activate the fuel pump. I dont know the names, but they are the 2 outside terminals farthest back towards the cab. (does that make sense?) After you jump it, you should hear the fuel pump turn on, its kind of a high pitched whining. After you do that you can look, listen, and smell for fuel leaks. Check around the fuel rails, that is usually where a leak happens.

EDIT: I'd say if you still can't find it then just keep an eye open but keep driving it.

Again, thanks to all who posted here... I really appreciate it.

Yes, "Ontario", it could indeed be the ever infamous "charcol canister".
Questions to ask yourself would be:
Have I recently "topped off" my gas tank, like, prior to noticing the smell ?;
Do I have over 20,xxx mis. on my ride &/or has it been a couple of years &/or 20,xxx mis. since either I or the previous owner changed the canister ?
Either or all of which "could" be the cause of the fumes, which has now dissapated due to either your running out the fuel or the canister managing to filter the excess gas out of itself.

Thanks for all the posts...
This really helps me do some repairing on my own or at the very least, does not make me sound like an uninformed idiot when I'm talking to my mechanic...
