The fuel filter is located in the fuel tank, pump removal is required to replace. There is an inspection cover behind the front seats on the floor to gain access to the pump. stupid idea. but whats not stupid about kia.

The fuel filter is in the petrol tank. You will have to drop the tank to remove the old filter. Make sure the tank is empty as it is plastic so you need to have it as light as possible.

The fuel filter for your vehicle is located on the Fuel Pump Unit, which is located in the vehicle fuel tank. The Fuel Pump Unit must be removed from the top of the fuel tank in order to replace the Fuel Filter.
