Oh, and speaking of vacuum pipes, where the one for the dump valve/BOV/recirc. valve, whatever you care to call it, runs across the top of the head (where the rubber hose connects to the steel pipe) there's another steel vac. pipe underneath that which has nothing connected at either end. What is that one for & more importantly to me, where should the pipes run to. I can't see any vacant connectors on the manifold anywhere but surely there's got to be something missing there...

Looks like someone's been messing before the motor was rebuilt as it was just put back as it arrived, which looks nothing like the diagram! At least I've got somewhere to start playing...
Just one more Q, what is the part on the fuel rail, numbered 23280 on the injection diagram? pressure regulator?
