i want to tap seperate lines for all my vacume/boost sources. the only question i have is how do you tap the manifold without getting metal deposits and crap in it. I want a separate line to my BOV and a separate line to my boost guage, i dont want to T anything. any help is appreciated

 

Run one fat short hose to a distribution block or vaccum resevior, t everything from it. Otherwise its remove manifold, drill and tap hole for fittings.
