This is one of the most frequent problems with the Optima model, not just one or two years but all year all engine size. You have one-two-three or four of a four problem set.
Your car has a canister located behind the rear drivers wheel called the EVAP canister. There are four hoses leading from that canister to:
1. The CCV or canister close valve. this valve allows for air pressure regulation within the close fuel evap system (filling your tank for example displaces air with fuel) and this valve is normally in the open position, but can get stuck closed. this is your number one suspect.
2. Back to the fuel tank, through a filter. This hose can get blocked from the charcoal releasing from the canister, or the two way valve can get stuck....
3. To the purge control valve. This can block also causing fuel to back up into the fill tube,
These three things, along with the evap canister itself, are your problem. It is a very easy fix with a jack, some jackstands and some metric sockets. There are no aftermarket for most of these parts, so i would search a site like carjunky to find some discounts.
The 2002 Kia water pump is located on the front of the engine. You can follow the bottom radiator hose directly to the water pump.

The fuel pump on a 2005 Kia Optima is removed by the fuel tank, disconnecting the fuel lines, and pulling the wiring harness. The pump can then be unscrewed from the tank, lifted out, and a new pump put in place.
Located inside the fuel tank.
It is in the tank. Remove the tank then the pump. Not an easy job.

My Kia Optima 2004 has the filter inside the gas tank. Behind the rear seats, when you fold them forward, you will see an opening to the fuel pump.
