P0456 Evap Code minor leak

So I've had this P0456 code pop up. A few months ago I replaced vapor canister vent solenoid and the gas cap. I'm wondering where else a leak may be coming from. I have 205k miles on it so I don't know if there is another common area where a leak might pop up. Could this be an issue with the purge valve at all. I'm not exactly familiar with the EVAP system, but I would assume it could be a bad hose or hose clamp somewhere.

Let me know if anyone's had any similar issues.
 


if you look under the back of the car where the gas filler neck is, theres two tubesm one fat, one small, the small one is the tanks vent, mine was rusted out and caused a evap code.
 
Could it be a bad vapor canister. I see that this is plastic unit that sits on top of the gas tank. I know the Vapor Canister Vent Solenoid was plastic and some of the rubber tubing could stand to be replaced.

I would assume the tubing here could be a culprit, otherwise could it be a faulty vapor canister purge valve or related tubing which sits on the throttle body I believe. I just want to make sure the points which could be responsible for the code.
