That's great Tim!
Dana was testing using resistance, and also using a '67 tank which may be different enough to measure a little different.

It's the last 1/4 tank that matter the most to me to be accurate......and that is the "dead' zone. not a lot of difference.... Gauge has 2 adjustments on it, and you can do some adjusting on the sending unit itself...
