They are not interchangeable. Always confirm the existing element number and housing series — matching the 1\"-14 thread and the 320RRAC01 housing designation is the safest approach. Also confirm whether your housing uses a reusable bowl before ordering, and inspect the bowl O-ring for wear at each filter change.\u003c\/p\u003e\n\u003cp\u003eRelated fuel system products: \u003ca href=\"\/products\/8131646816292\"\u003eSierra Marine Fuel\/Water Separator Filter 18-7862\u003c\/a\u003e • \u003ca href=\"\/products\/11095418994724\"\u003eSierra 18-7919 Fuel\/Water Separator Element — 10 Micron\u003c\/a\u003e • \u003ca href=\"\/products\/11095419027492\"\u003eSierra 18-99201 Clear Replacement Bowl — Racor-Style\u003c\/a\u003e • \u003ca href=\"\/products\/11095418961956\"\u003eSierra 18-7853-1 Fuel\/Water Separator Bracket\u003c\/a\u003e\u003c\/p\u003e","brand":"MISC.","offers":[{"title":"Default Title","offer_id":43563934220324,"sku":"S3227","price":46.63,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_e9c6d679-b2e2-44e8-a654-792d8e0b4209.jpg?v=1785960773","url":"https:\/\/marisolmarine.com\/products\/elm-s3227-fuel-filter-320rrac01-replaces-sierra-18-7948","provider":"Marisol Marine Company","version":"1.0","type":"link"}
