Water sensor for 7.3 Fuel/water filter system

[6 Nebraska IDIs]

I need atleast 3 of these things and cant find them anywhere. None of my ford dealers want to look, and my international dealer says they never used them.

Does anyone have the part number for this part?
This is the one that screws into the bottom of the fuel filters.

Maybe I found them, please check to be sure.
Will I need both of these?

when you buy the Wix 33617 filter, the O-riing comes with the filter.
I have a few extra WIF sensors.
It's yours for packing+postage.
