Part # 21008588 Fuel Filler Neckhttps://www.gmpartsdirectonline.com/.../21008588.html

​​Part # 21008336 Fuel Tank Vent HoseGet under vehicle and see what this part actually looks like. Depending on reason for replacement, you may be able to simply replace the hose section and leave the ends intact, as one end connects to the vent lines to the EVAP vent solenoidOr junkyard Part # 21008076 HOSE. Evaporation Emission System. (Fuel Tank End)
These hoses may be preformed but can probably be reproduced with normal fuel vapor compatible line.

Or junkyard.

Are you trying to solve an EVAP leak issue?
Throwing throwing parts at it is usually not the way to go. Try getting a smoke test performed or build your own smoke test rig.

The more connections you muck with in the EVAP system, the greater the chance that you will create a leak in addition to the one you are looking for. So yes you can try to replace all of this, but if you end up still getting an EVAP leak, is there a leak in the new components? Is there a leak where the new components meet each other?

Also, I believe the EVAP vent stuff is above the fuel tank. Dropping that is always fun and if I am correct will likely necessitate removal of some of these parts you are trying to replace to access other parts you are trying to replace.

Which begs the question, "why all this at once?"
