S4 OMP Question
S4 OMP Question
Hey Folks,
I am putting an S4 engine into my first gen car. Every thing is going well, but I have a question for you. There is a vacuum line onto the OMP injectors. What is that for? What does it do? How strong of a vacuum source do I need for this aspect of the OMP.
Thanks

It's not a vacuum line/lines. That is a source of clean filtered air for the injectors. It comes from a nipple on the throttle body that takes air from IN FRONT of the throttle plates.
It's the rotor side of the oil injector that is pulling air thru the injector.
