Anyone that has had experience and found a solution to the gas smell inside a VW I am looking at?  Owner suggests nothing can be done just don't fill the tank up..Checked with my brother in another state and he suggests that the vent tube might have a leak or in other ways be defective..

Like Russ said, there can be a lot of different causes.  Some models are more prone to gas smells in the cab than others.  Is it a Super Beetle?  If so, I've had a LOT of experinace trying to fix the problem . . . after changing out about everything attached to the tank, I figured out the problem WAS the tank.  With a full tank, gas would seep through the seam at the back of the tank.
