I heard that the fuel filter is permanent, and submerged in the fuel tank to cool it. Fair enough, but isn't it a bad idea to not be able to change a filter? What happens if it gets clogged?
I wouldn't worry so much about this filter. Modern gasoline and modern gas stations are "clean" with the rare occurrence of ingesting dirt/ crude from the filling station into your gas tank. I have cut open multiple fuel filters with 75K mileage on them and they have been "clean as a whistle". My tips to retain clean fuel...use top tier brands (do a search), keep vehicle fuel tank above 1/4 tank (well, not the typical Prius way of life), don't add fuel while the station is receiving fuel (or shortly thereafter) from a tanker. PS What sucks is AMG Benz owner's fuel filters. In tank, two of them, built into to fuel pump, about $400 each, plus labor. Some on the maintenance schedule every 60K miles. Again, I wouldn't worry so much about this Prius filter.
Oy vey, you've had the car one, two days, and you're researching fuel filter change? You're worse than me, lol. As far as I know the Prius c filter is in the tank, and as such best left alone if no problems point to it. That said, the Australian maintenance schedule does include filter change, and it's a bear.
