1991 wrangler smells like gas leak

Like mentioned above you need to look over everything related to fuel or fuel vapor, crankcase/pcv lines too. The couple areas that can be overlooked are the hoses to the charcoal canister, the injectors, fuel rail and pcv/ccv system

I have seen injector o-rings leak, injector bodies leak, pcv hoses disconnected or rotten, along with evap hoses (charcoal canister) Leaks around the injector are too common and usually not very big plus they can evaporate quickly, either check with the engine running or check cold after turning the key to on/run and check for dampness or residue.
