Don't trust your 'gas gauge'-Your gas tank bladder might be bad

    Yesterday my gas gauge went down to 'one blinking bar'-Almost running on empty.

    When I went to the gas station, I could only put in 6.5 gallons & the gas tank was full.

    I've heard about Prius owners not having an accurate gas gauge, because of the 'gas tank bladder'

    correct. as it stands, you don't know if the gauge is measuring lower or higher than expected.

    Inside the metal tank there is a smaller plastic tank and a bunch of different pipes to control the fuel vapor recovery system and fuei pump.

    Instead of a gas gauge we have a "guess gauge". I just stop and fill up when it's convenient after the gauge hits two bars or the miles on the trip meter hits 300 miles for the current tank. Absolutely no stress that way.

    or it said it was empty when there were still 5 or 6 gallons left
