13B rebuild question
 

Hey everyone,
So I'm in the middle of my rebuild and yesterday I was cleaning my center iron and broken one of the two primary fuel injector diffusers (I attached a picture for reference). My question is, Does the motor really needs this part or can I just remove them altogether?
