Where could I find the fuel filter on my 2004 Sonata 4cyl.

 

If the 2004 Sonata is the same as the 99 then your fuel filter should be located on the underside of the car somewhere in the region of the driver side door and the back passenger door. It's a tight fitand a hard job to do if you do not have your car up on a lift.

 

In the gas tank.
Don't service it until your fuel pump goes out.

 

Some people say it's in the gas tank, some don't. Anyone know for sure?
