QUESTION: I have checked under the rear seat a dozen times and I am 100% sure it is not there.

Answer
In the event there was a production change and the shop manual hadn't been updated, I also checked the 2005 Accent shop manual with the same result.  I also went back and checked the parts catalog again.  Although the fuel filter above the tank is shown for the 2004 model, there's also a filter on the pump assembly beginning with vehicle produced 9/1/02.  The fuel feed tube also shows a change beginning with that production date.

I suspect that the shop manual is incorrect (production changes often don't appear) and that the parts catalog erroneously lists the above-tank filter as applying to your car.  If you inspect the car and can find no filter between the fuel pump assembly and the fuel rail, then I expect the only filter is the one on the fuel pump assembly inside the tank.
