    You can replace the o-ring on the top of the tank behind the knockoff wheel or whatever I reg re use no problems . If I have it I ll put . the plastics snap off as fast as I type this no shop time .

    I also get easily 300K in changeable pump toyoda's . So it's rare for me to really change one of my own .

    Most important number is "voltage difference" during high amp loads from hard acceleration and hard braking, especially when going down a steep hill. Those numbers will show how soon pack will fail better than any other numbers. Please have a passenger help you obtain those screenshots while you're driving. Or DIY it if you think you certain you do it safely.

    Great advice, on Friday the 75 out much colder.. No problem. I think you're right.
    I called Battery Place. Hoping they will test it, and I think you're correct about the heat and the battery...it was brought the only way I could afford..rebuilt...1 year warranty..up 7/31.
    I got a simple plan as well. Because it's really old hi miles car 232k.
    , replace the fuel pump anyway. I still smell sulfur on heavy takeoff on the highway. I will pay the $100 labor and get that aftermarket cat. Installed anyway.
    Even yesterday, my MPG was poor. When it's nice out, it always gets a lot better.(cooler)
    On this car. Gas mpg was never great unless I worked burbs.
    Bringing the battery to my attention was a great idea...if I had to guess, I think now the battery could be weak under heavy use only.
    I do Uber in the city. Thank you..
    Hopefully, the battery guy calls me back Monday and I can get a replacement.
    I don't go down steep hills. So I accelerate heavy and hard braking with Dr. Pruis app. screenshot the #'s. I will try that..

    Just be careful with the logic with this model it'll leave ya carless or not driving very quickly . And not being capable financially or mechanically you can get taken really quickly with these models of Prius . If you've got the above enough masse no worries .
