14-18 GM Truck Billet Vacuum Fitting
This fitting gives you a clean and simple solution to get a vacuum/boost reference from your factory intake manifold. It bolts into place where your factory evap line goes. Then you can route a line to your BILLET VACUUM SUPPLY BLOCK, or directly to your wastegates, blow-off valve, boost controller, ect.
The 8AN 90* fitting can be used to mount a vacuum block directly to the intake manifold.
