                                                           You can smell gas for a few reasons.  One is you have a leaky fuel injector, simply replace with a new one.  If you have an older car, you could be running your carbureator a little rich.  Simply adjust the mixture by turning a screw on the carbureator.  If this doesn't work check the ouput of your fuel pump.
