so I have done a rebuild and put together the engine whole nine. Anyways when i went to start the motor it will have a very high idle (5k anyone?) and people have been saying vacuum leak. I think i have a vacuum leak at my primary injectors in how they seal.

Anyone able to explain how to seat/seal injectors ? pics are greatly appreciated since I don't understand every acrnym used on this forum.

what i did was place the little injector bleed in place, then added this small little spacer looking part on top of the bleeds, then set the injector on top of this all and tighten it down. In my eyes it never looked like it would seal as the diamters of it all were different and I didn't have a proper example to copy off so i basically just put it together how i thought it might go.

I'm probably going to take this all apart tonight and get pics of my set up so maybe that will help you all diagnose this issue with me

-RC 750cc injectors
-S5 LIM
-S5 center iron
-Stock Primary fuel rail, using the spacer part on the center iron

There are o-rings that should make the seal.

seen here.

you can also pick these up from an auto parts store, sometimes the factory/aftermarket factory replacement o-rings don't fit aftermarket injectors, when in doubt take the Lower manifold with and pick from their o-ring box.
