I guess where you are confusing me is left EGR , etc.

There is only 1 EGR valve and it is at the right/rear of the engine ..that line connects to the SOV valve . The other SOV [ piggy-backed on the EGR one] feeds the AIR valve. That is the one I think you are referring to as an EGR valve. That is ahead of the EGR , closer to the SOV, and it is inthe pipe from the AIR pump. And both of those SOVs [ Switch Over Valves} are fed with the single /white plastic line.
The U shaped rubber line on the engine/left side goes down to the black plastic line that is way down on the left/front frame rail.
And the Fuel pressure regulator [on top of the fuelrail ] goes to one side of the Y connector.
You want the vac schematic????????
