Fuel cell vapor problem

[70TWO NOVA]

Hey Guys, I have a problem. I have a vapor issue coming from my fuel cell in my Nova. I park the car in the carage and after driving it the garage smells of fuel really bad for about a week. Its so bad it gets into our house as well. (wifes not happy about that) currently the cell is vented to atmosphere but is there a way to keep it vented but get rid of the vapor smell? Charcoal cannister like the oems? or something? Any help with this would be appreicated. Im kinda concerned from a safety stand point too
