I can see that useful when your overall resistance is wrong.

ie a 29 to 91 resistance vs the 10-80 you need. mismatched sending unit to gauge.

but the issue I keep seeing is that it doesn't read right through part of the travel. As mentioned above. It reads full. but doesn't transition correctly and suddenly you are at half a tank. and it suddenly goes to empty.
I don't see this helping with that, as it would be a variable resistance problem though the travel.
