Fuel Tank Removal

You could have the tank cooked out to remove any sludge, you may want to get a new tank if your budget will allow you to. install a new sending unit and gasket. Don't forget to replace your fuel filter. It probably would be a good idea to rebuild the carburator too. Your car looks like it is in decent shape, my dad has a 1966 Barrauda Formula S, 273 4-speed, it was his first car. Good luck!!
