Here is a picture of where filter is located......Then at filter you will need to barrow fuel filter quick disconnect tool to slide into fitting at filter so it can be removed. Let me know if you have questions, thanks.
I was thinking of a different model....This vehicle does need no tool, there are tabs on the retainers that connect to feul filter....Just press them in and slide it off....If anything you can use a hanger bent in shape to help press in the tabs. Here is a picture of filte with tabs to press. http://www.kia-forums.com/attachments/1g-1994-2002-sportage/2764d1214318211-gas-filter-removal-02-kia-ff.jpg
