I ordered all the parts to upgrade my original LQ lines. I have the original saddle clamps and I am assuming that I need to replace those with one of the "62175 Male Adapter Nylon Fitting". How do I drill out the hole? Do I have to tap? Also, Rabbit's post has this quote "You will need a 1/4 inch NPT pipe tape to do this right." What does this mean?
Thanks in advance.
