tubing. Remove blue wing nut from top connector of foam nozzle and slide it on the blue tube with the threads
facing toward end of tube. Slide blue tube all the way over the top of the small tube on foam nozzle. Slide wing
nut back to the threads and hand tighten. Follow the same steps for the clear tube and tube nut.
