Re: 48-50 fuel sender idea

The bimetal operation is unique and as far as I know only used for a couple of years by some Ford products, Packard and a couple of others. Good to know you did confirm it is not available.
I did some experimenting with one several years ago and captured the operation on an oscilloscope. I am not familiar with a compressive disc type sender and don't believe Packard used what I would consider compressive discs like the stacked tablet like carbon disc resistance such as used in some 1949-50 heater switches.
The universal Ford straight resistance 78-10 ohm senders do work but they need to be modified. Some stock Ford units of the mid 50s work as is but you do need to make sure the tank depth and length of float arm is the same. Ford had several model senders for their various size tanks. Before Kanter repro'd the 51-6 senders I experimented with one of the universals and following instructions that came with the sender to adjust the float, made other modifications to mount the universal sender on an original sender flange so I could install it in my 56.https://packardinfo.com/xoops/html/downloads/56fuelsender.pdf
(Note that the part numbers and price of the Universal sender I used and quoted in the article is no longer accurate.)
