2000 T6 S80 - Fault Code P0442 and P0456

[BVPepper]

Hi All, Solved a few problems as a lurker, however first time poster. I have a 2000 S80 T6 - 149,XXX mi. seams to be running fine as usual. Check engine light on...pulling P0442 and P0456 - "Evaporative Emission System Leak Detected (very small leak)". I have the "page 2" detail info, but I'm not sure how relevent that additional info is at this point and to be honest I don't know beyond the initial code what it means. I didn't see any other threads in this forum with these key words so I'm wondering if anyone tell me what parts/systems I should look at first?
Thanks for looking!
