need help having problems figuring out what these connect to

#1 - i know this is a fuel line and i know where the end connects, but the end with the rubber hose connected and the arrow pointing to it, where does it connect to?
#2 - i think this is an oil line, there is a rubber hose connected to it, but not pictured, where is it supposed to connect to?
#3 - this is the bottom nipple of the oil filler neck, what is it supposed to connect to?

 

OK
the bottom nipple on oil filler connects to the plenum of the primary turbo via that hard pipe.
and the other is actually on the diagram that you have posted the three hard pipes to the right of the coils is what you are looking for.

 

the bottom oil filler port indeed connects to the hard pipe pointed out in the second picture, which should connect to the inlet of the front turbo (since the other is connected to the manifold and has a check valve in it, it doesnt vent the gasses while there is positive manifold pressure whereas the the other allows the vaccuum being drawn by the turbo inlet to provide the ventilation)

The fuel line one is the fuel tank vent it should go to the charcoal canister.

 

thanks guys
