Fuel Filter Location on 2003 Kia Optima

Can anyone tell me where the fuel filter is located on this vehicle. The parts stores show an inline canister filter but the dealer said that the filter is in the tank... what gives.

This is what I found in the Fram catalog. It looks like an in-line type. It will either be under the car or in the engine compartment. Here's a picture if that helps.
That's the style that I bought, it was a Wix, but I have been under the car front to back and have no idea whree they could've hid that thing... Anyone want to buy a Kia... Cheap!!
