It is possible for the float to be intact and not float. It can fill with gas. It is possible you have a bad float. It may also be possible the float arm is stuck on something keeping it in the full down bottom of the tank position. If you have not had the tank completely out and empty and looked around in there, perhaps you have something in there interfering with the motion of the arm.

I don't understand this sentence at all. I think OER is a brand name, but I don't know what you are trying to say.

There is measurable resistance when in the empty position.

Ohms measured with an ohm meter between the sending unit terminal (with wiring disconnected) and the sending unit metal mounting plate should be near 0 ohms when the float arm is down (empty tank) and near 90 ohms when arm is up (full tank). This makes me wonder how you measured.
I wonder if you can use alligator clip test wires to connect the sending unit to ground and to the sending wire while the sending unit is outside of the tank, and then watch the gauge while moving the float arm, and see if it seems to read correctly. I would probably tend to try something like that. With the sending unit removed that is your chance to look around in the tank with a flashlight. Siphon the gas out of the tank if necessary, and look around in there, to determine if the tank is nice and clean and free of debris. And it is possible you need to make minor adjustment to the bend of the float arm to keep the float from rubbing on or contacting the sides or bottom of the gas tank.
