Hi Rigga;
As I said, it's for the instruments, so what we are trying to do is have pitot and static lines clearly marked to avoid confusion. I'm pretty certain that there is a Boeing spec for the tape, but as I don't have access to any of that kind of info here, and all of my vendors want a part number before they can go out on a search, I am not getting anywhere fast at this point in time.
Thanks for the ATA idea, I shall explore that one.
