I already replaced the gas cap due to getting a message n the dash (tighten fuel cap) I am still getting the message and now my check engine light is on. I had the code read and it is coming up large leak. I am not leaking fuel. So I would think t is my evap valve. Where is it located?

For codes reading 0455, the fuel evap valve is located under the rear of the truck close to the passenger side wheel. Follow the fuel hose to the large box under the vehicle, and look to the right of it. It is about the size of a soup can with a couple of hoses and a wire harness leading to it. I just came from the dealer. Cost of the valve is $48, and labor was $140. Took less than an hour. Description was "large evap leak detected. Evap valve stuck open. Found by using smoke tester"

Where is the location of my evap canister? For years I have seen them under the hood, but not on this model. I need to change out the purge solenoid that bolts to the canister.
