There is an external vent ( outside of the trunk) on the tank too, but if the car just sits on a hot day the fumes will get into the car, this is what I'm really after.
The focus of the exercise is to vent the tank so fumes don't get into the car by the venting. There is an external vent but by capturing this I hope to clean up the car.
How does the manufacturer of the fuel cell suggest venting? There is usually a vent associated with the filler pipe.
You don't smoke do you?
