Drilling & Tapping Intake for Boost/Vacuum

[Mohammad J. Baig]

Instead of drilling into anything, here is another
idea.  I have a 93 Miata Turbo....to feed the boost
guage I tapped the rubber hose coming from the brake
vaccum booster....it works, and is easy to Un-Do if
you screw up....

Just an idea....
