Fuel sending unit performance

I have rebuilt several sending units over the years but not a single one gave me a challenge like the one in my, or any other Packard I have restored. I found one that would work in my 49 but would only read 1/2 tank at best long after the whistle I love so much quit alerting me it was full and ignoring it, trying to test the other half of the gauge. I could drive for days and the needle set at 1/2. Being one of the quirks of the car, I accepted the fact once the needle started moving, Better get gas in the next 100 miles.

Now I know. The other night, the gauge was setting at about an 1/8. I stopped for gas and it was windy as hell. Put the gas nozzle on full and ignored the fact the factory alert whistle stopped. About 30 seconds later it spit gas all over me. (Yes I was standing down wind) It burnt like hell the rest of the way home and lighting a cigarette was out of the question and the gas gauge went to empty.

When I got home I decided to make a patch panel to take place of the sending unit since it quit working anyway, and tear it apart. I made some amazing discoveries. They are extremely serviceable and and adjustable for any tank or voltage. I'll add some pics if anyone is interested.
