You're right...you shouldn't smell anything if it is working normally. It is designed to trap fumes, but once it is fouled with liquid fuel, it will no longer trap fumes and so any leaks will become very obvious. This used to be a common problem on my previous SUV...a Nissan Pathfinder (great truck).
