Welcome to GreenHybrid.com.
Yes, the North American Prius have a flexible bladder in the fuel tank. This helps reduce the gas fume emissions. However, it can result in substantial differences in fill volume. But as a result of my gas studies, it seems to have taken out a lot of the variability (click on my signature to see the record.)
I hope you find useful information here and would be interested in a synopsis of other forums. I've been trying to keep the Prius FAQ current but other than PriusChat and the YahooGroup "Prius_Technical_Stuff," I don't get much.
Thanks,
