I just got injectors back from Wes Ingram. Unfortunately the PO did the disassembly of everything so I get to put the puzzle back together a bit blind. I guess installing SPICA injectors is pretty straightforward since I can't seem to find much info or threads on the topic.

Here are my questions:
  1. Is there any seal besides the copper o-ring that goes between the injector and intake manifold?
  2. Any thing else required for injector installation to ensure there is no fuel leakage at the injector?
  3. Is anti-seize a good idea here since there's steel mating with aluminum? A little reluctant to do that in this application.
Thanks!

Hi,
Only the one seal between injector body and manifold.
Ensure the hard lines are installed straight and square to the inlet on the injector.
Anti-seize is always a good idea.
And remember - no need to over tighten!

And, don't forget to install all of the little support plates & bolts. Without just one, an injection line will vibrate and fracture (ask me how I know).

I've taken apart about 6 sets of intake manifolds with injectors and a few I'm sure have been sitting around for decades in open storage boxes. I don't recall one injector being so seized that it could not be removed without too much difficulty. So the anti-seize might be unecessary in my opinion....unless you anticipate the engine being exposed to extreme environmental conditions for extended periods of time.

That seems to be the answer then. Thanks!
