Gasoline smell

I have a 2000 XJ cherokee with a 4.0 L. It has just over 100,000 miles on it. What I'm experiencing is the smell of unburned fuel after driving it. I checked all the fuel lines and injectors with no sign of a leak. The jeep runs great and doesn't have any check engine light issues. If anyone can give me any info I would appreciate it. Thanks, John

Had the same with 89. So bad you could smell the thing 30ft away in a parking lot. Changed all the fuel lines, no fix. Finally had a shop smoke test it. Small leak in the rubber filler hose, tightened clamp. So far so good.
