I placed several gallons of fuel into my new alloy fuel tank vented with Mocal breather vent valves.

Today, I had a very strong fuel odor in the trunk (boot). Apparently the Mocal valves only control fuel passing not also closed to the atmosphere as I originally thought.
I have contacted Mocal and asked for an explanation of the vent.
I have plugged the vent hoses as they exit the car.
If that is not a temporary solution to the odor problem I will unplug the vents and seal the filler cap vent. As the vent hose is 5/8" fuel line and new, I doubt the fumes are permeating through the rubber. The filler neck elbow is also new and installed correctly.
Its back too the drawing board. The fun of Lotus restoration
