Interested in which gauge you pick. I need to put one in my crew cab.
Good luck with the troubleshooting.
I can't imagine the pickup end getting air under those conditions, unless there was a defect in it higher up.
Any chance the tank vent could be getting blocked? Doesn't seem likely though.
Only other thought was a connection in the shutoff solenoid circuit, but sounds like you checked electrical first.
If it was a gas rig I'd be thinking about water in the bottom of the tank, but diesel filtration would mitigate that.
