Check for fuel leaks, I would bet it's coming from the modded fuel rails if there isn't an actual leak. People who have done braided fuel lines sometimes have the issue of gas smell when not using good braided lines. So if fittings used on you fuel aren't that good it could be coming from there

Can you get a better picture of the fuel rail setup?

Looks like they blocked imgur from work...guess they want me to be productive or something...Anyway they are PRJ Performance rails, no visible leaks from any of the fuel line connections that I can see and after touching all around the lines no fuel smell either. Do believe it is coming from the engine bay though as I dont notice the smell when using recirculate with the heater after the smell clears up from cracking a window, also really only notice it when I come to a stop light not necessarily always driving.
