Metering oil nozzle vacuum lines
 

I'm removing most of the vacuum solenoids and lines on my FD to go single turbo. I got rid of the whole mess of metal vacuum tubes. Does anybody know where the vacuum lines going into the metering oil nozzles should connect to? Do they just go to manifold vacuum?

I have an FC but it has one vacuum line from the upper IM to the this "spider" which leads off to 4 smaller lines each going to an oil injector. Check the vacuum diagram under your hood.
