i was trying to install the fuel injectors in my block today, and i have every thing set up right except for the insulators.

I have a broken one, and I cant exactly tell what they are. I have something in my gasket set that looks like the bottom of one but i'm not sure.

Could someone point me in the right direction as to what these insulators are made of, or how to put them together etc.

 

I'm having trouble visualizing what you're talking about.
