Gas smell

I have a 93 Wrangler and notice a strong gas smell sitting at lights.I can't find any leaks or a dried up spot anywhere,any ideas.Could it be running that rich and if so how do I fix it.

Check the lock ring that holds the fuel pump to the tank. It may have loosened and could let fumes out and water and dirt in. It happened to me.

I think csaw44 is on the correct path. But need more information. Do you smell gas in the garage when its parked over night? or only when its running and stopped at a light?
My old CJ would leave the garage smelling of gas but no puddles or leaks were to be found, wife complained enough that I finally dropped the tank and found that it was almost swiss cheese with rust (how it didnt leak amazes me) replaced the tank and hoses only to find that it started smelling AND leaking after a few days, my spanner nut that holds the fuel pump and sending unit came loose (or I didnt put it on right). Re-enstalled it and the leek and smell went away.

Also check the Charcoal canister. It collects the raw gas fumes. It's possible that the vent line going to it is cracked.

The best advice is about testing for the smell while parked. If it gets worse while the engine is running, then it's something related to the fuel feed side....

Also, does it seem to mater how full the tank is?

First, lay off the beans.
Second, with the engine running smell the exhaust fumes (not long or you'll end up like me) and look for gas leaks, return line and such.

Try checking the fuel supply line (could be the return) where the hard pipe out of the tank changes to hose (drivers side). You may not see a lot of gas as it tends to evaporate quickly but you will smell it. Tighten the clamp. Eventually the clamp will loosen to the point the gas will start to puddle but it could burst into flames before then too.
