Sorry - I guess I should already know this, but what is the "bladder" and how does it differ from a conventional gas tank? Sounds intriguing.......
Someone posted this earlier (see attachment). Essentially it helps eliminate the evaporative emissions.
That's really cool- thanks! the pics are great too. This is ust one more thing that makes me like my Prius so much...Do any other cars have this type of fuel tank?
<div class='quotetop'>QUOTE(patsparks @ Oct 12 2007, 12:55 AM) [snapback]524479[/snapback]</div> Partial zero emission under California regulations... one step below (above?) SULEV.
Yeah, my window sticker says "AT PZEV" or "Advanced Technology Partial Zero Emissions," which is lower than SULEV, and sounds cooler. Thanks for that doc, Evan, I hadn't seen that one! Cheminee, here's a thread with some fun pictures of a Prius gas tank being taken apart: http://priuschat.com/index.php?showtopic=31545

It's best to not sweat the "absolute" quantity of fuel in the tank. On my 2006, I know that a half tank takes about 4-6 gallons to fill, which makes sense. I don't bother running down to one or two pips. Nor do I care about trying to achieve a high mileage before refilling---when it's convenient, I fill up. Usually that's at the half-tank time. On the slowest pump setting, I have enough time to wash the windshield. And I never try to "stuff" more fuel into the tank. When the pump shuts off, we're done. On a few occasions, a pump just won't cooperate: it keeps shutting off and I have to change pumps. A few times, a pump hasn't shut off automatically. When the last pip begins to flash, you don't know how much fuel is left. The remainder can change with temperature. So all you know is to buy fuel now.
Thanks for the link Ichabod- I never cease to be amazed by what the Prius has inside it...... :blink:
