The gauges to my belly tank and two saddle tanks on a 1974 46' Hatteras Convertible are inoperative regardless of fuel level. I am a new Hatteras owner having moved up from a 28' Bayliner so I am unfamiliar with "common gripes" that these boats might have. If it is a common thing, is there a common fix? Any help would be appreciated!
