Fuel Tank Venting Question

The filler tube vent on my '64 looks like what is pictured, but I have no adjacent holes in the trunk floor to route a hose through. I believe I will drill a hole just behind the wheel tub and run a hose through there.
The vent in the filler tube faces forward at about 10:00 if you look at it from the fill side.
Should I loop once around the filler tube before dropping down or just go over the top toward the back of the car and down?
