Geswek that pic is seriously sharp gotta be the lens .
I did the same thing on my 13 as vacuum source for the Tial BOV on my HotPipe Kit .
I wonder if it'll be OK to T into that Brake Booster line further upstream closer to the booster itself for a secondary source . I know you told me a few days ago your doing the Hotpipes as well but hadn't decided if your gonna do OEM or Tial BOV .
I still haven't installed my center pod from Crash yet for the boost Guage , coolant and tranny temps either .
Pondering on the secondary source though .
By the way I used 3/8 inner diameter braided fuel line to Tial and the barbs at all three points are 3/8 O.D.
Its kinda buried in the install info for the HotPipe kit.
