Strong Fuel Smell
Sounds exactly like mine. Was a cracked fuel sending unit. Sometimes the barbs that the hose attaches into gets brittle and starts to crack. I actually could not see any visible crack in mine. Went around replacing the O-ring and tried to replace one of the fittings that attach to the barb since I was for sure it was an o-ring inside the fitting that was torn or something.
Nope. Wasn't until I replaced the fuel sending unit that it was solved.
Hope this helps! I dealt with my issue for nearly 6 months. Finally fixed it a week before I sold the car.
