I need some fuel sending unit experts please

No.

It actually mimics the electro mechanical units functionality.

Have you with the sender removed from the gas tank and grounded, plugged the oem sender wire into the sender and moved the sender arm through it's range.

I will try the working aftermarket sender that I replaced with this latest one. It’s out of the car so I can easily ground it and hook it up to the connection wire to see how it works. It reads 10 - 73 ohms as I run it through the full arm swing range.
