What little hat? The metal bell mouth on the end of the injector that goes into the cylinder head? If so, you don't have to have it. Injectors have different designs. Can you take a picture of what your talking about? If you mean the lower injector seal, then yest you need that, they are $1.19 each from the stealership. I just got 4.

He's probably refering to the pentle's. They're used to create a tighter seal in the insulator. You don't really need them but you can get them almost anywhere.
