What is this sensor above the oil filter 5.7gxi

[Fireman78]

i need to replace this sensor it is completely rusted. It’s located just above where the oil filter(or remote oil filter attachment) is. See the pictures

Could be a knock sensor if your engine is set up to use one.

Ayuh,..... I believe that's an oil pressure port,...... knock sensors go in a water port,.....

I'm guessin' it's either an oil pressure sensor for a gauge,.....
Or,....
An oil pressure switch for an electric fuel pump,.....

That's the oil pressure sensor.
