Inspect all fuel lines, fittings, and the mounting surface before installation. Use the supplied gasket and verify all fuel connections are secure and completely leak-free before running the engine.

When a customer is replacing an older pump, the inlet and outlet port locations on the later design can differ from the earlier versions, which may require fuel-line changes during installation. Always confirm the bowl orientation and port layout match the original before finalizing the order. A common customer mistake is ordering based on engine displacement alone without verifying the pump configuration — some 3.0L applications used different pump orientations depending on engine vintage and installation.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324693741604,"sku":"8M0073435","price":461.17,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/00d2a6f1-ea66-4eae-8ba4-d1781b3ddd99.png?v=1788239416","url":"https:\/\/marisolmarine.com\/products\/merc-910","provider":"Marisol Marine Company","version":"1.0","type":"link"}
