The boost gauge can also be installed by drilling and tapping the intake manifold horn to 1/8-27 NPT. First, mark the drilling location on the intake manifold horn using a Marker and a Center Punch. 2. Remove the intake manifold horn from the truck to ensure no shavings enter the intake during the drilling and tapping process. 3. Starting with a 1/8” Drill Bit, drill your pilot hole into the intake manifold horn and gradually step up in drill bit size until you reach the size R Drill Bit. 4. Take the 1/8-27 NPT Tap and slowly tap the size R hole in the intake manifold horn. Clean the manifold horn with a Vacuum to remove all shavings. 5. Prepare the boost hose for installation by installing the compression nut and ferrule fitting over the boost hose. Tip: Wrap Teflon tape clockwise on all male threads. 6. Install the compression adapter into the 1/8-27 NPT hole you tapped using an 11mm Wrench. Using a 3/8” Wrench, tighten the compression nut onto the fitting until the boost hose is snug. Note: Do not overtighten. 7. Route the boost hose up to the firewall to the driver side of the engine bay and use zip ties to secure the boost hose to ensure there is no contact with any direct heat source or moving parts of the truck.
