I have made an issue to change P/N 169593G (Fisher S201) to be P/N 209167M (Fisher 99) in 2014 (as I remember).
Once in 2015, there was agreement between PTTEP and SOUER, but in that time P/N 209167M did not included in the agreement, still continue with P/N 169593G
and it was recommend to updated to be P/N 214517.
I would like to ask you a favor, the CS800 Regulator can be trade back for Fisher 99?
Then PTTEP will be correct detail for order once again.
