I need to know where the EVAP valve is located?

I have a Hyndai Elantra 2002 American version. Motor 2000 cc.
The check was marked on the panel and took it to Scane. Gave error in Evap. I called Group Q and bought the Evap valve that is in the engine. They told me that it has two. One in the tank that is almost never given, that the one that is damaged is the one in the engine.
My question is where this valve is located exactly, to be able to change myself. And if there is anything more than to do when installing it. Or if there is any procedure for it.

Thank you

It would be good if you add a photo because those that I know are like great and look at the naked eye since they arrive or leave a black deposit with three or four hoses.

I can't annex the image. But annex this address. There comes the image of the valve.
