the fuel gauge shows low fuel, however there is fuel. Do I need to repair it or can I just watch mileage to be sure not to run out

Hello, if there is indeed a problem with the fuel expectations in mileage, then testing should be performed to find out why this is the case. Yes, you can always judge how much fuel you have based off of more and other factors than the fuel gauge, but it would definitely seem like having an accurate gauge reading is something that would be pretty helpful and essential.
