So I wanted to vent my optispark. But my car is supercharged. I don't need help on the inlet side( fresh air). It's the vacuum side.. can I run the vacuum side in factory location but just with a check valve in place.. how's everyone else running there's on their boosted lt1 engines

 

from your other thread did you try this?

Well the factory harness for the vacuum side those already have one way check valves correct?
