The copper washer is for the drain plug, the metal one you can put in your "spares" bin. The rubber o-ring is meant to go under the filter housing lid. Take it off and you'll see the old one around the groove just under where it flares out to fit on the housing. Always lubricate the new rubber seal with fresh oil before putting it on the filter housing lid. The metal seal is in there because on the older models, you had to replace the seal on the stud that runs down the center of the housing cap. Hope this helps!
