Here is thr only break down I can find which is the 648 dollar part, item 17 (item 2 on your image) I have and am not planning on using as don't need it for CAI On my car, again it's used but if your interested send me a conversation.
Out of curiosity do you have the complete item 1 as that valve is part of that hose assembly, not sure how you remove as one hold up for me starting my CAI conversion.
Call a Dodge dealer and ask for the price on a purge control valve. That's the name of the part. It can also be called an evap purge valve. I didn't see any part numbers or availability in the aftermarket for Hellcats. But, the cost for one a Chinese made part on an SXT is about $40 at AutoZone.
