I have a quick questions for those that have FIC injectors. What do the numbers engraved on the injectors mean? Does 850-125 mean I have 850cc's? That is the same number engraved on all four injectors I have. Also, is it normal for it to have two o-rings on the top, one black on green? Finally, if I wanted to can I replace the green o-ring with a factory one?

Thanks again!

Use the orings that are supplyed with the injector other wise they probably wont' seal up and you fuel pressure will be incorrect due to leaks especially when pressure rises.
