Witco Fountain Tubing

Does anyone know or have pics of how the water supply tubing is routed on Witco fountains? Curious if it goes up the back of the tiki (on the outside) then straight through from back to front or is there a hole bored in the tiki from bottom up to the mouth?

This link might help. There may be another post about it somewhere as well.

Mahalo! I'll ask Sputnikmoss over on that post for a pic or description.
