I wanted to fill everyone in that uses these t-stat housing part numbers. Here is what I learned as the 12678779 is now a non-active part number.
In place of 12678779, use the housing 12678780, and seal 12623519.
My shop foreman states the pipe 12669654 is rarely needed and not necessary, but available.
