Do those need to be there?

I received mine back from RC with blue plastic caps on them that cover the entire side surface of the injectors. The holes on the bottom are still the same.

I am just trying to figure out if I need to remove those or leave them on there...

thanks

 

Pintle caps? I'd leave them on, but I don't know why they are there in the first place.

 

Yeah.. I'll take a pic of what I am talking about tonight.

 

I believe they are there only to keep the bottom O-ring on the injector
