we recently had to bleed the line on our furnace from running out out of oil and after we tightened the nut its slightly dripping from it .

When bleeding line using most times a 3/8 wrench you should open line hit reset and catch the unused oil in a can to replaced in oil tank . when closed it should stop right then . Maybe dirt under bleeder screw try to loosen when running just a bit catch the oil and tighten again.
