Fuel gauge wiring question

@S'cuder You can use a 10-32 die with a drop of lube to clean those rusty contact studs. It's a tedious chore since a handle wont go there. Fingers only. My 10-32 die from Harbor Freight just barely fits between the studs. The factories stamped tin nuts contact only 1 thread of the stud. Since they are hollow, they don't plant the standard ring terminal very will either. That's why I would go to Home Depot and get the little orange bags, internal toothed washers and true 10-32 hex nuts to attach my wires to the gauges etc... Less than a dollar per package. Just be careful in tightening the nuts. No power drivers. That fiber board is easily broken. The studs are just swedged into a square hole. Good luck
