The way it is diagramed out there it looks like the fuel pressure regualtor is supposed to be T'ed into the air duct, intake manifold and EGR solenoid? I can't understand why this is. Why would you want the FPR connected to anything other than manifold vacuum?
It seems to me that you'd want the fuel pressure regulator connected directly to the intake manifold only. The line from the air duct then should go straight to the EGR solenoid. So instead of having the 'C' male to male connector you should leave the two systems seperate.
As soon as I get my NX up and running I'll try doing it my way and report back.
Well, my diagram is the simple way to do it. If you notice, I have not added anything to the FPR line that wasn't already there, OEM.
The main goal was to illustrate the simplest way to get rid of the AIV and BPT stuff for use on a JDM intake manifold.
If your goal is to get the FPR on one vacuum hose, then you can do that, and there are countless other ways to reroute your lines, including bypassing the charcoal canister, blah blah blah.
(BTW this is how I had my old DE-T running, with my boost gauge on the FPR, and everything was reading normal back then.)
