The 3847644 is the higher-capacity replacement and is taller — on some engines there may be clearance considerations.

The part numbers look similar and the filters are physically close in size, which leads to mix-ups. Always match to the full engine model code and serial number, not just displacement.\u003c\/p\u003e","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":43564016402468,"sku":"3847644","price":33.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/9361b45e-77a9-4590-a7a6-037d2573a325.png?v=1778203693","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-3847644-fuel-filter-water-separator","provider":"Marisol Marine Company","version":"1.0","type":"link"}
