Re: Replacing fuel sending unit on '55 Clipper

For a long time there were very few Packard senders available (and still are not for many pre 51 models) but after the need became apparent and the xref info to Ford products that some found would work was entered, Kanter had the 51-6 senders repro'd. As far as I know they still have them but since the repro tanks he had done about the same time have run out perhaps senders have too. Maybe James could confirm if they are still available or not.

Problem with the Ford units is the float arm length is apparently different because Ford had several tank capacities and shapes and it is only a specific Ford product that will work. I don't know if the xref details on which sender will work is correct or if those who posted an item did any rework such as you did to make them work.

Packard used King-Seeley thermal gauges in 51-6 and those need an ohm range of approximately 75 empty to 10 full. Some Ford, Chrysler and AMC models used that range too. By going directly to ground I would be worried the gauge heater could burn out but if it is grounded only when the tank is absolutely full maybe not as big a concern. Still, unlike the 0-90 or 0-30 GM ranges their gauges needed or the 100-0 obsolete S-W range used in some pre 50 Packard models 10 ohms was there for a reason.
