How do you install the primary injector?
basic question.. I always installed my primary injectors with combination of o-rings that sealed fine, and I recently learned about the stock plastic piece with mesh that needs to be underneath the primary injectors. How do I install these parts in correct orientation and sequence? The block is 20b D-series which atkins rotary told me should use the FD style injector parts as seen.The primary injector holes are bare metal holes without any plastic or rubber sleeve. Thanks in advance.

I thought this would've been a very easy question

found out those things are called the fuel injector diffusers. Do you guys even use them with rebuilt engine? or just skip them like I did from the beginning?
I was hoping this would help with low rpm cruise.

I think the outer face of the diffuser faces the center of the engine (if I can say so) so it can provide a more uniform fuel mist into the combustion chamber.

The diffuser is keyed so it will only go in the right way. The rubber seal goes around the end of the injector and basically seals it to the block so you don't have an air leak there.

You only need them for OEM injector and rail, as mentioned above the diffuser is keyed so it only goes in one way, then the rubber O-ring goes on the rail, it kind of sit between the rail and the block to fill that gap.
I see an EV14 in your picture, if you are running after market rail with EV14 then you don't need any of that.

because if I do this, it blocks that tiny air port on the side of the injector hole in the iron. and it doesn't keep the injector perfectly straight and centered.. there's really nothing to keep the end of the injector centered in the injector hole in the iron.. is there a thick o-ring that goes where the groove is at the bottom hat of the injector?
sorry... just never seen how it's supposed to look. I never used the diffuser before. thank you.
on the upside, the diffuser fit like a glove. thanks everyone!
