Check fuel cap light

[Al England]

I recently bought a 2011 ram 2500 wit a 5.7 . I drove it for a few days then got a check fuel cap light. I replaced the cap and the light is still on. Google said to replace the evaporator valve @the tank. I got under the truck but it doesn’t look like the video. I can’t find the valve that looks like the one in the video. Can anyone give me advice as to what I do next
