repair or replace fuel filter on a 2001 Hyundai sonata
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
under the fuel tank
It is inside the fuel tank.
The fuel filter on a 2002 Hyundai Sonata is located just outside the fuel tank. It is positioned inline along the frame of the vehicle to protect it.
On all Sonata's from 2004 on the fuel filter is in the fuel tank. The fuel pump is mounted inside it and according to the dealer it is a "life time" filter that they only change when replacing the pump or if fuel was contaminated.
If you follow the fuel line from the fuel tank to the engine you will find the fuel filter unless it is a permanent filter that is located in the fuel tank. I suspect you will find it has a permanent filter.
In the fuel tank
The 2008 Hyundai Sonata with the 2.4L engine has a fuel filter installed as part of the fuel pump assembly. To replace the fuel filter, it is necessary to access the top of the fuel tank (in the trunk area) where the fuel pump resides. Be sure to disconnect the negative terminal of the battery at the appropriate time, for safety. Check HyundaiTechInfo.com for more information.
