Help Identify Fuel & Oil pressure sensors (Service Bulletin)

I went to perform the service bulletin for the leaking sensor issue and step #1 is writing down the part numbers of the sensors. I went as far as removing them and there is no identification at all on mine (Garmin G3X Touch system).

What are these?

All 3 of those are Kavlicos. If you look hard enough you'll see stamped part numbers on the flats.

I've had them out in my hands jut like yours. No marks whatsoever!!

That would be a bit disheartening as how do you know which pressure rating sensor you have installed.

My sensors that came from Garmin all have similar part# stamp as it is shown in the picture.
