Fuel Filler Neck seal

[Ramgiddyup]

Hi-
I have a CEL P0456. When I go to check the Gas Cap, I noticed the seal on the fuel filler neck is cracked. I believe this is what is causing the code.

When I search the web,Autozone,O'Rielly, for this part, nothing matching to a 2010 Dodge Ram 1500 Hemi.

Does anyone know what this part is called? Can I replace just this part, or is it the entire fuel filler assembly?

Words I have sued to search for this:
Fuel Filler Neck Seal
Fuel Filler Neck Gasket
Fuel Gasket
O Ring
Fuel O Ring

That’s not going to cause your code. The sealing surface is between the O ring on the cap and the actual filler neck. That’s just a weather seal, not part of the emissions system.

Warranty right....? Drop it off. Get a loaner.
