Just for giggles, went into the garage with a flashlight, and popped the connector off. The stud on the sender seemed shiny, but the connector came off awfully easy. Perhaps a fine layer of corrosion adding to the resistance? Next above-freezing day, I'll try cleaning the hole in the connector, and maybe gently squeezing it a tad to tighten it up.
