Jeff you must be reading my mind. I was about to post a question about the benifits of the rubber gas tank. So here goes.
What are the benifits of a rubber gas bladder? I understand that bladder can contract as your car uses gas up thus saving gas vapor from escaping. The amount of vapor in a 11 gallon tank maybe comes from a few drops of gas (my perception, someone correct me if I'm wrong). Isn't this a shot gun aimed at a fly? I assume traditional cars just have a vent in the gas cap thus letting gas vapor escape 24 hours, 7 days a week. Wouldn't a metal tank and a gas cap with a one way valve be better? Just letting air in as gas is pumped out to the motor. The trade off being at fill up. You would release some gas vapor but then no more guess gauge, no more bladder contraction problems.
Any comments?
