Abstract
A variable resistor useful for automotive type fuel senders has a cermet film fired upon a refractory substrate. The cermet film is burnished to reduce asperity of the fired film. The resulting resistor element works with existing mechanical float type senders to provide a reliable and long lasting sender.
