fuel gauge send unit

[kurt v]

Are the fuel gauge sending unites up to 1955 compatible with the 1940 king sealy senders ?

Kurt: According to Googler the answer is YES. The gas tank sending units are the same. Read about it here:

Yes, they are --- all 6 volt.
All you will need to do is save your current extension for the unit. (where the connector is) and connect it to the new sending unit.

Ford used them up into the early 60s. They all work on the same principle if electric. Ford used instrument voltage regulators after 1956.

King-Seeley fuel gauges and senders are all interchangeable through 1955 (there are two generations of the internal sender design but that is not significant). 1956 is a standalone one year only gauge and sender design (terrible design) and is incompatible with anything else though they at first glance look identical to 1955 and pre. 1956 senders are all dual spade and always stamped '12v' (there are 1955ish 6v senders that have dual spades but have no stamp which differentiates them from 56)
