I have done several injector replacements and I have never see injectors with 2 O rings on any of the injectors, primary or secondary. Also, those blue caps are put on when the injectors were shipped, I believe they should have been removed before installation. I went with the FIC stainless injectors and they have performed flawlessly.

I did not use any permetex on my gaskets, the gasket should seal fine by itself. If you ever need to put the plenum in the future, it will make plenum removal easier and no need to replace the gasket.
