I just did a pump on my 02 Santa Fe, I actually found it by accident, but I had to take out the rear seats. then pull up the carpet and liner, and there is a panel under where the passenger side seat was, just take it up and you should see the fuel lines and the electrical for the pump.

The fuel filter is located in the fuel pump which is in the fuel tank. It is tha same for as the 2001 Hyundai Santa Fe.
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
On the 2001-2006 Hyundai Santa Fe (4 cyl or V6), the fuel filter is a special "long life" type of filter located in the gas tank. It is better known as a "fuel screen", or "fuel strainer", that surrounds the fuel pump. The filter is generally only replaced if/when you're replacing the fuel pump.
The regulator is part of the fuel pump assembly.
The fuel pump is inside the fuel tank on a Hyundai Sonata.
Take your rear seat out,pull the carpet out of the way and there's a door with a few bolts holding it. Take it out. There will be another thing with eight or nine bolts.....take it out and you should have your fuel pump out. Hope this helps.
The fuel pressure regulator on a 2005 Hyundai Elantra is located on the fuel pump inside the fuel tank. To change it you must remove the back seat. Under the seat there is a axcess panel through the floorboard to the fuel pump. Un hook the fuel lines and wiring, remove the screws that hold the pump to the tank. Lift out the pump from the tank. The pressure regulator is on top of the pump.
