Default Engine swap questions

I'm putting a 95 into a 93 shell.
I'm right in the middle of the swap and have a few questions in regards to the intake manifold vacuum lines...

on the 95, a vacuum line goes from the fuel rail to a sensor, and then to the intake manifold... since i'm using the 1.6 electronics, that doesn't use the sensor is it ok to go direclty from the fuel rail to the intake manifold?

orange circle (fuel rail)
yellow circle (sensor)
red circle (intake vacuum line)
purple line (direct vacuum connection between fuel rail and intake manifold, which is what i'm planning on doing)

2nd question.
i'm deleting the egr sensor blue circle with an x but right infront of it is a vacuum line fitting, where does that go to? i compared it to the 1.6 intake manifold and the 1.6 has 1 less vacuum line fitting then 1.8.
Is it ok to block it off? (light blue circle with question mark)

3rd question.
I used the flyin miata egr sensor block off plate, but i'm wondering if i can block of where the 1.8 egr tube goes into the intake manifold?

i tried searching and looking at pictures of other people who did swaps, but i'm still at a loss... any help would be greatly appreciated.

just in case anyone asks this same question,

you can go directly to the intake manifold from the fuel rail...

the vacuum fitting in front of the egr is for the auto tranny and can be blocked off.

you can make a second egr block of plate, or leave the tube connected, but be sure to block of the hole in the exhaust manifold as well if you are blocking the tube off on the intake mani... for the exhaust manifold i just welded it shut
