Customers occasionally land on this listing while searching for gasoline-engine fuel pumps because it is listed under the broader MerCruiser brand. If the engine is not a 6.7L diesel, this is the wrong pump. For confirmed 6.7L diesel applications, always match by engine serial number and the Fuel System – Mechanical Pump and Fittings diagram before ordering. When replacing this pump, inspect the full fitting set — O-rings and banjo bolt seals are common post-service leak sources if reused.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563915280420,"sku":"8M0112244","price":119.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6db8afdd-cbb2-4ba1-8514-295078eb5463.png?v=1773119115","url":"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-mechanical-fuel-pump-8m0112244","provider":"Marisol Marine Company","version":"1.0","type":"link"}
