Yep, on the sedan it's under the drivers side rear. If you follow the fuel return line where it goes back up thru the floor into the tank, the vent valve will be just a couple inches away from it. It's attached to the metal line from the tank with a short piece of hose - a pair of needle-nose pliers will work to undo the clip and let you pull the whole assembly off.

But if the car has stock tires, unless you're thinner than Twiggy, you'll need to jack the car up on that side to even get to the bloody thing. Another reason I love 205/70 tires.
