Re: sending unit

There has got to be something else that used a similar sender because Motors calls it out as Ford and King-Seely in their description.
Repairing one looks a bit more complicated than the typical rheostat used 1951 on because there is also a heater in the tank unit in series with the gauge unit. Even though both Packard gauges are bimetal with heaters, senders may not be compatible because of different ohm readings--1951 on ranges from 10-70.
I have a sender in a NOS box for the smaller tank, looks identical to the one pictured in the operational description, but the readings are hard to judge. Ohm reading of the sender heater appears around 13.5, however it is erratic -- from 13 to over 100 so either the contacts are opening and throwing off the reading, or the gauge even though supposedly NOS is faulty.
At any rate, if there is a Ford person who has access to older manuals that might show a sender unit, if one is found resembling the picture it might possibly work -- if Ford used a similar depth tank. The sender does not appear to be easily adjustable because Packard listed another unit for the larger 20 gal tanks.
