Just measured my Subaru sending unit.
52 ohms empty and 2 ohms full. There are 2 sending units in series on the Subaru tank, so 104 ohms empty to 4 ohms full.
I have a 12" tall tank that I am filling with safety foam, so I can't use the Subaru or Boyd (float on arm) type sending unit.
I am using a VDO unit #224-229 which is 90 empty and 0 ohms full. This will read pretty close, but I can add a 10 ohm resistor to make empty read perfect.
