My fuel gauge has never worked well since I got the car. It responds, but swings rather unpredictably during the first 1/4 to 1/2 of the tank, then by about 1/2 full until truly empty, the gauge reads empty. Since no one reproduces these, I still haven't found a fix. The part number B7A-9275-F is for all cars and Thunderbird, except sedan delivery, station wagon and retractable. B7A-9275-C is for sedan delivery and station wagon. It looks like B7A-9275-G might have superseded B7A-9275-C when the Ranchero was introduced, but I'm not sure. B7A-9275-B is for retractable.

The folks at Concurs list B7A-9275-C for sale. They claim it is for all cars, including sedan delivery and station wagon, except for retractable. I've been emailing to figure this out. The vendor who provides it to them lists it as B7A-9275-F, but Concurs decided to market it as B7A-9275-C, and Concurs continue to state that it will work for a wagon. I'm very skeptical.

Has anyone tried this? Even if it is the wrong part, could I transfer the arm from my old sender to the new unit and end up with a working system?
