My Pantera and my GT40 share a garage, both have Holly carbs and braided lines and the ONLY time I ever get a smell of gas is after filling the GT40 tanks full. I've learned not to top it up and no problem. In my case I'm pretty sure it is a poor seal at the top of the flip caps and I don't have the recommended modern fuel-cap upgrade (sure would appreciate more info on if there is a GTD retrofit...), which I am confident would eliminate the problem altogether.
