I could not find the fitting to replace the one on the tool side and my 3/8” vinyl tubing would not fit over the fitting, even when heating it, too rigid. Instead, I used 3/8 silicon tubing and that worked perfectly.I did not replace fitting on the cta tool. Just attached vinyl tubing to it and secured with clamp. On other end of tubing is barb included in Merlin kit (link below). It attaches perfectly to Motive (use some teflon tape).
