GSX-R1100 Overflow Part 3

So last night before heading home, I made a negative pressure takeoff pipe on the lathe
and drilled a hole in the intake manifold for a press fit—you can’t get it in without using vise power★
There’s a step to prevent it from coming out, so it’s tight.
 

 
I secured it with adhesive that works on rubber and metal.
Now I can sync it with a vacuum gauge even with forced opening and closing!
