Hi
From my rusty memory the early Sprite senders (Moving iron type dashboard gauge) were about 0 to 70 Ohms resistance. The later senders (Thermal type dashboard gauge) were considerably higher in resistance.
The Austin senders were more like 0 to 30 Ohms. So your gauge reading may not be the most accurate in the world, but it's a lot better than nothing !
You might consider rigging up sender and gauge temporarily out of the tank, and moving the float by hand to get an idea of what reading to expect.
