Auto Meter Gas Gauge

73-10 if you are using a FACTORY sender but THERE ARE NO (that we know of) replacement senders that are accurate. You might need what is called a "meter match" or repair your old one if it is factory

Biggest problems with "repops" is some have too short an arm and don't "move" fully through the tank, and the resistor is not the correct "taper."

(Common old school "taper" for resistors is linear, logarithmic, and what is called "audio" taper used in volume controls)
