Re: Fuel Tank Only Filling up to 7/8
That's not particularly abnormal. I have a 16.3 gallon gas tank. If I fill up when the indicator says low fuel, it takes just shy of 14 gallons.
The standard gen 9 tank is 13 gallons, the indicator says low fuel when you have about 2 gallons left (give or take), so filling 10.5 gallons isn't surprising. Plenty of gas pumps are more sensitive and shut off sooner than the manufacturer intends.
With that said, if your car's computer and gauge cluster shows it's not full, then the fuel level sensor is incorrect.
