I found this in my dash cluster and the way they have it named you would think it is for how much fluid you have in your tank, kinda like a gas gauge but it isn’t?

If your still driving it like that without any warnings then could possibly be tuned. Mine appears that way on the cluster.

Wives tale.
In over 45 years of driving I’ve have never had a single in-tank fuel pump failure and have run the gauge below empty many, many, many, many times.

I'm assuming you're joking. There would have been lots of warnings preceding it getting that low.
To be fair, he said it's his dad's Jeep. He may not know about DEF in modern diesels. And it could be tuned so it's turned off.

Where does he say it's his dad's?

I read where he states "I found this in my dash cluster"

Pumps need the diesel fuel to lubricate. Gas fuel not so much.
