Using the 24” section of hose, slide the 11.3 mm pinch clamp onto the hose and install the hose onto the barb fitting installed in step 13. Tighten clamp.

Route the free end of the hose to the actuator valve on the exhaust. An extra elbow connector and clamps are included if your routing requires a sharp bend at the actuator valve. Use if necessary. Slide the supplied green spring clamp onto the hose end and install the hose onto the actuator valve. Slide the clamp onto the actuator valve barb. See section circled with red in the picture.
