When the fuel flow is steady, the boat feels alive — crisp throttle response, smooth idle, effortless acceleration. Mercury Marine part number 866170T01 delivers that kind of confidence. This low-pressure electric fuel pump supports your engine the same way a good deckhand supports the captain: quietly, reliably, and without drawing attention to itself. Whether you’re running offshore swells or cruising calm inland water, having dependable fuel delivery means the entire boat just feels right.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eProvides consistent low-pressure fuel delivery.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eV8 MerCruiser engines\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e with Gen III Cool Fuel modules.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt from durable marine-grade components.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIncludes pump and connecting accessories.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered for clean, efficient fuel flow under all conditions.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eFits \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e305, 350, 377, 496, and 502 cid V8 MerCruiser engines.\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eGen III Cool Fuel\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e equipped sterndrive engines.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for performance boats, cruisers, and tow-sport vessels.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with both saltwater and freshwater applications.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eA fuel pump like this doesn’t just move fuel — it shapes how the entire boat feels. With steady low-pressure flow, the engine breathes easier. Starts are quicker, idle becomes smoother, and hesitation under acceleration disappears. You’ll feel it immediately in tight maneuvering and especially when you roll into the throttle to get the boat on plane.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThis OEM pump is built to handle the heat, vibration, and constant demand of marine use. The internal components resist wear, and its electrical connections are designed for stability in high-moisture environments. Because it’s engineered specifically for Gen III Cool Fuel setups, the installation aligns perfectly — no awkward fittings, no guesswork.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eReplacing an aging pump often brings an engine back to life.

With an OEM pump, you know the pressure output, electrical characteristics, and fitment match what Mercury intended — and that precision helps protect injectors, fuel rails, and the Cool Fuel module itself. If a fellow boater asked whether aftermarket was worth the risk, I’d say no every time. This is one of those parts where OEM simply delivers the peace of mind you want when family and friends are aboard.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFAQ\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ1: Which engines does this pump fit?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e It fits V8 MerCruiser engines with Gen III Cool Fuel modules: 305, 350, 377, 496, and 502 cid.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ2: What makes OEM better for fuel pumps?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Exact output pressure, correct electrical connections, and long-term durability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ3: How do I confirm it’s right for my boat?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Verify engine model and confirm you have a Gen III Cool Fuel module.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ4: Works in saltwater too?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Yes — it’s built for full marine exposure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ5: Easy for most boaters to install?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Yes, though having access to the fuel module is necessary.\u003c\/span\u003e\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46935727767843,"sku":"866170A01","price":332.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/866170a01_main.jpg?v=1760631286","url":"https:\/\/partsvu.com\/en-ca\/products\/mercury-mercruiser-fuel-pump-electric-gm-v-8-engines-866170a01","provider":"PartsVu","version":"1.0","type":"link"}
