There is a vacuum hose from the charcoal canister (under the front, left fender) that traces up to the throttle body. When it breaks, you cna get the fuel smell.

Also, trace the fuel supply and return lines under the ar. Look for "gooey"-ness of the undercoating. gasoline dissolves it, making it gooey. Indicates a rusted hard line.

When I had this problem, it was because of a bad deal of the

gas filler cap. You can replace it for a couple of bucks. I had

one of those key storage caps that didn't seal well.

Your fuel filter is on the drivers side. If is smells like raw gas you could be leaking at a hose or something. If it is a rich running smell then I would guess your oxegen sensor but you should get a check engine light on the dash.
