you wont know the extent of the fuel leak around the fuel rail unless you pull each fuel injector OFF the fuel rail...Those O-rings go bad..U will see a mustard like crust around the o-rings to reveal ur leak..Gas evaporates remember?...Replace ur O-rings as well as the small L shaped rubber hose found on the passneger side engine wall...Right below the E-BOX

Keep in mind could be the injectors themselves, especially on higher mileage vehicles. Over time, with heat, the plastic gets really hard and may develop cracks. I just replaced all 12 injectors on my 750 for that exact reason (smell of gas, checked all injectors and the connectors were actually wet with gas). All perfect now.

Behind the pass wheel-well under the floor is the 3/2 valve for the return to the tank. (Emissions)
Leaks in this area are quite common. The pump is under the rear seat. That would be a real strong eye burning smell. Then down to the floor behind wheel-well to the valves and filter then up to the rail.
