Thanks JFP in PA. I looked at this article on Pelican.

Pelican Porsche Tech Article - Replacing Your 996 Fuel Line Vent Valve / Bleeder Valve - Porsche 911 Carrera & 986 Boxster - Porsche 996 Carrera (1998-2005)

I do not get any of these symptoms and never had a fault code show up on the Durametric from it.

If you are having trouble filling up your car with gas, your check engine light keeps coming on, your car will not enter a “ready state” for a smog test, or you hear a howling sound like someone is blowing across the top of a Coca-Cola bottle you may have a faulty fuel line vent valve.
