Fuel level sending units

Their ohms range is the same 80-10.

Well, that's the theory anyway.
Never seems to work out from doing mine and seeing issue's that others are having.
I got a brand new sender and what was supposed to be the matching guage and it doesn't read right.
If I fill it up it takes close to 80 miles before it starts coming down.
It's accurate as it gets closer to empty though so I'm ok with it.
