Had the very same problem with the SS unit from Auto City on my '62 After installation of the sender & new tank added 7 gallons of fuel. Checked the gauge & it read almost empty! Ended up adjusting the float rod like "ben" & it now reads 3/4 full after fill-up & 1/4 full when 1/2 full. Called Auto City about the problem & of course they had no issues with that unit. Verified that the resistance is correct, 0 - 30 ohms. May just add a 5 ohm resistor to the gauge wire as readjusting the float arm is a rear pain even with a lift!
