It was a question that boils down to: "I got this fuel cell with a 0-100 ohm fuel sender. But my vehicle's control unit needs 450-100 ohm input. I can't mess with the sender. How do I adapt it?"
It's an electronics question. There are no off-the-shelf solutions, and this requires a circuit that emulates a 450-100 ohm resistor, based on the input from a 0-100 ohm fuel sender.
It got migrated to Motor Vehicle Maintenance & Repair (https://mechanics.stackexchange.com/questions/88464/understanding-ohms-resistance-and-how-to-tell-a-fuel-float-gauge-to-tell-the-o#616173).
Sure, the problem is presented in the context of an automotive application, but it requires a custom solution that is entirely in the purview of electrical engineering. The best I can tell, it appears to be off-topic in MVM&R, since MVM&R is not about electrical circuit design.
I consider the migration to be unwarranted. At best, it's presumptuous in assuming that the asker should perhaps look for some "other" solution, where no other solution exists: they got the stuff, they gotta make it work somehow.
