Re: Stumped on Fuel Gauge

Alright fellas, I need some help here. I’ve swapped two senders, two gauges, ohm’d out the sender wire, checked all grounds. I’ve manually moved the sender by hand and watched the gauge respond. When I first start the truck for the day, the gauge reads correctly, but when the engine gets warm, the gauge goes back to E….

I’ve troubleshot a lot of wiring issues in my time, but I’m stumped. Only thing I can think of is something is heating up and causing resistance to change. What could it be?
