2001 Kia Optima when you go to put gas in it it spills out the filler neck, it take 20 min to put in 5 dollars of gas. I have tried to stick a wire and hose down the tank with no sucess

Tried to get a PIC but KIA provides no info. But valve will be one of two places either on top of tank or in a hose that goes from tank along filler tube

My daughter has an 02 Optima that had the same problem. Ran several hours of troubleshooting including removing and checking the cannister, which was fine. I finally found a 1-way check valve that was installed backwards (at the factory). As soon as I disconnected the valve, the pressure instantly released. We reversed it and the car took fuel normally. The valve has the flow arrow molded on it. It should point toward the fill cap, not to the tank.
