I'm not sure I agree. I believe that's an electronic sender, and needs to have 12V fed into it to work right; then it simulates the appropriate resistance. I think I'd put it back in-circuit and measure the voltage across the sender as you raise and lower it in the tank - no change, new sender.

That's already a replacement, and not the one that came with the boat.
