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!

when i got mine it said on the box to use the o-rings that came with the injectors and not the stock ones. just thought to let you know.

 

Use the rings that came with the injectors.

 

Ditto. They came with the injectors for a reason .
