This sender assembly (tank hanger) is not available anywhere new (at the time I did this), and sending it off to be
rebuilt could take months & cost ~$300. But I found that some of my old ruined Bronco & gas F-series senders use a stainless backplate that screws to the FDM & tubes. So I flattened one out and welded it on. I ordered some
2mm stainless rods (3/32" or 2.4mm probably would have been better) and bent one to match the original. Since the original float keeper was also Carbon steel, and I don't have any thin SS sheet, I snipped the end of a SS hose clamp, spread it with a pick, and pushed that onto the rod. Then I flattened the rod to make sure it doesn't slip off.

New senders have recently become available.
