1. A hole must be drilled and tapped into the intake crossover pipe for a boost source.
2. Remove the hose from the intake crossover pipe and push a rag well into the pipe past the point to be drilled and tapped. This will prevent chips from entering the engine.
3. Drill through the back side of the crossover pipe using a letter “R” (.399 dia) drill bit just above the turbo compressor hose joint.
4. Tap this hole with a 1/8 NPT pipe tap to accept the fitting.
5. Use grease on the drill and tap to allow a minimum of chips to fall into the crossover pipe.
6. MAKE SURE TO REMOVE THE RAG from the crossover pipe and clean out any chips.
7. Install fitting and connect hose making sure hose fits snug but does not pinch.
