There certainly has to be a leak somewhere if you smell the fuel. It may be very small and/or someowhere you cannot see. It could be something like an injector that has a solenoid issue and leaks fuel into the cylinder after the vehicle is turned off, this is not the best example as I do not think thisis the problem but I am trying to push the point that there is an issue, just not something you can see or find easily.
Often gas leaks will be hard to find because they evaporate almost immedialtely especially if they are small and/or near something hot. A fuel leak is always a danger and could start an egnine fire, so don't give up on finding it. One way you could at least look for it without the eninge heat helping to conceal it by evaporating the fuel from heat. Turn the ignition to the, "ON" position and do not start the vehicle. The sytem will get pressurized by the pump and you may be able to find the leak more easily now that you can put your hand in areas where it is normaklly to hot and the chance that the fuel may evaporate off a hot suface is not an issue. Also, feel around all the fuel connections you can find. You may not see the fuel dripping but you may be able to feel it seeping out of a connection.
Good luck and keep looking.
