2. Measure a length of 1/4” ID tubing to connect 1/4” ID barbed tubing fitting in the siphon cartridge port and the
vacuum input open tee of the Vac Sensor (see Figure 2-13). Plan enough tubing to avoid sharp bends in it or
stretching it. Cut and install this tubing and secure tubing ends with spring clamps.
