    M73 V12: Delete the vacuum system for the injectors

    Well, my original injectors have started disintegrating (plastic fantastic).

    These injectors are unique, with a vacuum nipple. Unfortunately, these injectors are also expensive, and times 12 it adds up.

    Has anyone replaced these injectors with regular style injectors, and capped the vacuum system? Is the vacuum part of the injector necessary for regulating the flow based on vacuum?

    I have the pre facelift 750 but as far as I heard those are not vac lines. Those are positive pressure air addition lines to add air to the fuel spray. I doubt the DME cares if they are the old style but the adaptations would probably care since the original injectors had more air in the fuel mix which would probably mean the car would run poorly until adaptations caught up.
