Another newbie question,

So I filled the gas tank for the first time on my new to me 2005 S40, and when I pulled the nozzle out I heard what sounded like a sucking sound coming from the tank. Never heard that on a car before.

Do these cars have some built in evaporative vacuum system to capture the fumes coming out of the tank during a fuel up?

Are you sure the sound wasn't coming from your wallet? Sorry I couldn't help myself. :)
