OEM Fuel Sender Accuracy

I filled up today and thought I would share.

I have a 70s OEM supersedes fuel sender (the one that is shaped like the aftermarket ones) in my 18 gallon tank - 67 Dart.

The gauge needle was exactly 1/2 way between 1/4 and 1/2 tank or 3/8

3/8th of 18 gallons is 6.75 gallons in the tank


18 - 6.75 = 11.25

I filled up till the nozzle clicked off and put 11.203 Gallons in.

I think the factory knew what they were doing!
