Injector Color Marks?

[rlibraman2k]

I am going to buy some black mark injectors off of EBAY but I think that I have white marks on my injectors--Can anyone tell me what the flow rates are for each type of injector marks on the 94 Q45 injectors?--Will I have problems if I switch my whole injector rails to the black injectors?--I have seen red, orange, green, white, black and injectors without a stripe--Pleas let me know ASAP--thanks

Welcome to NICO.

Don't think the rotary injectors are color coded. But used injectors are just that, used. May be out of specification already, or if not, very soon.
