What are these for? (FD)

[Welsh Dan]

I'm in the middle of my single turbo conversion (from parallel twins). However, whereas these bits were connected to the intake before, where do I connect them to now, if at all?

They're the bits in the circles at the top and they sit just behind the lower inlet manifold on the top of the engine, either side of the pulsation dampner thingy

I've read on the yank forums that these can be left open to atmosphere, but there seems to be different views on whether they are plumbed into the induction or capped or just left open.

Maybe someone who's already crossed this bridge can help, mine won't be ready until next summer!

they're the vents for the OMP injectors. They need to be open to atmosphere but filtered.
I tee'd them together and used one of the small filters in the defunct rats nest.

I left them venting to atmosphere but when i took it too WGT pip told me to plum them in after the airfiter... see diagram attached.
