Thanks Baker,
If this is a common problem, would be worth checking out. Increases in the air gap would definitely drop the output voltage.
Your brother doesn't have a scope/scanner by any chance does he? lol You could have a look at the waveform and see what is happening. With these types of sensors, they sometimes employ what's called a floating ground. You'll know if backprobing one wire only gives you half a picture.
Backprobe both wires of the sensor and run it through the one channel. Output is in AC voltage.
If all the leads are original or the same age, I would replace the lot. Your rich running can definitely be contributed now to at least a partially burn knowing the leads are shorting to ground.
Fuel pressure looks good. System not losing pressure, due to leaks etc.
