Bringing this back up. Going to be re-installing my gas gauge. Can I confirm the placement of the brass slip ring(s)? One goes between the outer nut and the gauge. What type of gasket goes in the opening of the tank?

Did you by chance get a new star nut, if so...they are trash and will not seal, got to find a original.
