That could be a failing charcoal canister. It is a large, coffe can sized filter that is supposed to trap all the fuel odors and emissions from the tank by drawing it though a charcoal media. When it gets saturated, you smell gas. The "emissions passer" items basically help clean the catalytic converter so that it is more effective. It won't fix a bad cat, it won't fix bad injectors, it won't fix tune up issues, all it will do is help scrub the catalyst to make it a little more effective.
