gas fumes in cabin

I have a spf mk2 with a single 4 barrel 427 fe and under certain condition's I get gas fumes inside. I also get the fumes in my panterra. Is this the nature of mid engine cars? Looking for ideas. I have put 900 incredible miles on my spf mk2 in the three weeks since delivery and It is simply incredible ( except for the gas fumes) mabe the gas fumes just make me think the car is incredible.

Hi Jerry,

The forum is divided into subcategories and there is a forum for fuel related questions. I'll move this post into that forum.

Might want to use the search feature. I think you'll find it is from the carb itself, tank vents, or filler necks.
