Rb25Det Neo Vacuum Lines

[RB25DETC33]

Hey guys, going over the engine in my R34 I have noticed a few open lines around the 25. Had a bit of a search around and found out a couple of them bu I am not sure about these ones...

Fuel Rail Hard line....this one isn't hooked up, fuel system has been modified and has a fuel pressure regulator fitted.

Plenum underside vacuum hose looks as tho it was meant to be part of the fuel system

Power Steering vaccum line from looking at diagrams from the workshop manual it looks like it just connects up to the cooler piping? Is this correct? I have a pretty ordinary cooler piping kit hooked up to this car at the moment. (how I bought it)

Any help would be greatly appreciated.

After studying my gfs r34 i have worked out the lines. The fuel rail and the plenum ar actually the same line. The hose is connected to the other end of the hard line. The piwersteering line does infact go into the cooler piping. Afm side of turbo.
