I tried to look under the hood, couldn't find any leak, I tried to rev the engine, but still no leakage and even no smell under the hood.

When I walked around the car, I smelt some strong gas odor from the passenger side rear wheel fender, so I guess I have leakage in the fuel pumps or fuel filter.

But does it make sense? I mean when I was driving, how could fuel odor from rear get into the air vent?
