Default Re: What's inside my tunnel?

Early on when I started investigating gas fumes in my bug, my Dad (a VW mechanic from the 60s/70s) told me that sometimes gas sits in the tunnel and can stink up the car. I'm guessing provided there is a leak or bad seal or perhaps fuel could just penetrate (leech through the poreous medal) through the medal tube and fumes be held in the tunnel.
