1999 Hyundai Entourage

Hello, I have a 99 hyundai elantra. I'm trying to locate the fuel filter. I was told it is in the gas tank and access is made under the rear seat. I located this and opened it up and located the fuel pump but no fuel filter. The filter I bought looks like an inline type of filter and I have searched under the car and in the engine compartment but still cannot locate the filter. Thanks for the help.

Chris.
