Well, I think I may have this resolved. Original issue was a float that wasn’t floating. I corrected that, but I think maybe the swing arm wasn’t contacting the tank wall.
Jon’s suggestion of a little twist/ correction with two adjustable wrenches did the truck. A full tank reads full at roughly 34 ohms. We will see how it does as this tank empties.
Have to give the gauge a tap to get it to return to empty when key is off. It might be a bit sticky, I guess.
