uhm...why can't I see the black/white valve then? Thought it was pretty obvious what I was on about by the way phil, as everyone on here calls it a checkered black white thing...
But for me goes the same, my fpr also runs a seperate line under the inlet manifold...
you lose that when you do the full bypass mate! you right in what you call it but if you have seperate lines for it all then you no longer need it.
