Thread: MFI injector

  1. #1

    MFI injector


    I'm planning to change all MFI injectors on my 911 E-73, after I have discuss with Bosch that you cannot repair or adjust injectors who are 45years old. How to change just bring them out and put the new in place
    Thankful for advise if you have done this operation

    Unscrew the old, make sure you get the copper washer out, it may come out with injector or it may stay in the head. You can reuse them, put some anti-seize on the threads and install the new ones. Also put some anti-seize on the fuel line threads. You should have old ones tested, they may not all be bad, don't just throw them out.
