The fuel filter in your Hyundai Sonata is in place to purify the fuel as it runs through the fuel injection system. This prevents blockages from occurring in the fuel injector and fuel-pressure regulators. To maintain engine health, mechanics recommend you that change the fuel filter once every 30,000 miles. The procedure will save you money and does not require the expertise of a licensed mechanic. It can be completed in less than half an hour.
