The 3039/33039 on the left has a large flange that seals with gasket on lip of glass bowl, holding it up from the bottom and I assume seals tightly by itself, I suppose with gasket.The Fram CG3 on the right does not have this flange and needs the spring to hold it flush to top of the filter housing.
