John,
That’s the set up on my Intermeccanica. The fitting for the vent line is just under the gas cap. Loop it after the fitting, then run the hose down and out.
For what it’s worth, VW based Duchess have a fuel tank on the right front floor plan (Classic Roadsters Ltd. did not use VW tanks). The tank was not vented. the car was in an enclosed garage. I never had any fuel smell in the garage.
