I need to replace the filter cup only.. Can I do this without replacing the entire housing assembly? My defective part is # 138 on the diagram. How would I remove the housing from the connectors in #140, and reconnect them?
Unfortunately you do have to purchase the complete filter housing assembly 218904404 to get the cup. To release the hoses from the filter head, you push in on the ring round the tubing and pull out on tubing at the same time you are pushing in.
