From a Hyundai dealer technician- there is no serviceable fuel filter on the 2003 Sonata. The filter is a "lifetime" strainer on the fuel pump in the fuel tank. It would be replaced with the replacement of the fuel pump only. how do you replace fuel pump on the 2003 sonata
Yes.
You must remove the fuel tank.
Change it every 50,000 miles. Not doing this can damage the fuel pump.
