There are so many posts of where you should and shouldn't tap into the manifold for a pressure source. Now it seems the best place I have found is the little piece of hose on top of the valve cover. But with everything being added more sources are needed. So far this is whats hooked up for a pressure vac source:

Boost gauge
TT (Blitz DTT)
BOV
Boost Controller
SMC alky controller

Thats 5 different taps right there, 3 of them pass through the fire wall. Now since it's time to start tidying up the engine bay does anyone know of a product or that have built one and willing to share with the rest of us.

 

I don't know what company makes it, but there is a vacuum manifold. That is exactly what your looking for.

Just google "vacuum manifold" you should find it. Actully I found it
