High-Pressure and Low-Pressure Fuel Pump Kit for Mercury Marine Outboard Engines, HFP-CPN11

HFP-CPN11 is a complete dual-pump kit built as a direct OEM replacement for Mercury Marine outboard and sterndrive engines using OE part numbers 8M0062770 and 8M0062771. It pairs a high-pressure pump with a low-pressure pump in one kit, engineered to meet or exceed original factory specifications for a straightforward, complete repair.

A Complete Dual-Pump Solution, Not Just Half the Fix

A Complete Dual-Pump Solution, Not Just Half the Fix

Marine fuel systems on these Mercury applications rely on both a high-pressure and a low-pressure pump working together. HFP-CPN11 replaces both in one kit, so a partial fix that only addresses one pump and leaves the other to fail later isn't a concern here.

Upgraded Internals Built for the Marine Environment

Upgraded Internals Built for the Marine Environment

HFP-CPN11 uses upgraded polymers, brushes, and commutators inside a corrosion-resistant casing, addressing the constant exposure to moisture and fuel that wears down standard pump components faster in marine use than in automotive applications.

Engineered for a True Drop-In Fit With Everything Included

Engineered for a True Drop-In Fit With Everything Included

HFP-CPN11 ships with the wiring harness and rubber grommet included, so the kit installs as a genuine drop-in replacement without sourcing extra hardware or adapting factory wiring.

Why Boat Owners Choose HFP-CPN11 From QFS


A fuel pump failure on the water is not just inconvenient; it can leave a boat stranded. QFS built HFP-CPN11 as a complete, matched pump kit so owners get both pumps, the wiring, and the hardware needed to do the job right the first time.

Reasons to Choose This Kit

  • Complete dual-pump kit replacing OE part numbers 8M0062770 and 8M0062771
  • High-pressure and low-pressure pumps matched to work together
  • Upgraded polymers, brushes, and commutators for extended service life
  • Corrosion-resistant casing built for the marine environment
  • Wiring harness and rubber grommet included for a true drop-in install
  • Backed by QFS's industry-leading lifetime warranty

What Problems HFP-CPN11 Solves


On a dual-pump outboard, fuel delivery trouble usually traces back to one pump failing while the other keeps compensating until it can't. Here's what HFP-CPN11 is built to fix.

Engine Loses Power or Stalls Under Load on the Water

Symptom The engine bogs, loses power, or stalls when you push the throttle, especially under load.

Cause One of the two pumps in the system is failing, so the engine isn't getting the combined fuel volume it needs at higher demand.

Fix HFP-CPN11 replaces both the high-pressure and low-pressure pumps as a matched set, restoring full fuel volume under load instead of leaving one worn pump to carry the system.

Hard Starting or Rough Idle After a Single-Pump Repair

Symptom The engine is hard to start or idles rough even after replacing just one of the two pumps.

Cause Pairing a new pump with an aging one leaves mismatched output between the high and low-pressure sides, so the system never balances correctly.

Fix Replacing both pumps together as a matched kit means the high and low-pressure sides work at the output levels they were designed for, from the first start.

Pump Corrosion From Marine Use and Ethanol Fuel

Symptom Repeated pump failures on a boat that sits in humid, salt-air conditions and runs on ethanol-blended fuel.

Cause Standard pump internals and casings degrade faster in the marine environment and under ethanol exposure than they do in an automotive application.

Fix HFP-CPN11's corrosion-resistant casing and upgraded internals are built to hold up to marine conditions and ethanol fuel, not just tolerate them.

Best For These Mercury Marine and Mariner Applications

HFP-CPN11 replaces OE part numbers 8M0062770 and 8M0062771. Confirm your specific engine model and year with the vehicle compatibility tool on the product page before ordering, since coverage spans multiple Mercury, Mercruiser, and Mariner applications.

How Every HFP-CPN11 Kit Is Built and Verified Before It Ships


Every HFP-CPN11 kit goes through a defined build and verification process before it's cleared to ship, so both pumps arrive matched and ready to perform together from the first time you're back on the water.

  1. 01

    Matched-Pair Assembly

    The high-pressure and low-pressure pumps are built and paired together as a matched set, using upgraded polymers, brushes, and commutators designed to extend service life beyond the original equipment they replace.

  2. 02

    Spec and Fitment Verification

    Each kit is checked against the 8M0062770 and 8M0062771 fitment spec, confirming the included wiring harness and grommet line up for a true drop-in install with no modification required.

  3. 03

    Final Inspection and Same-Day Shipping

    A final inspection confirms both pumps, the wiring, and the casing are free of defects before the complete kit ships, with most orders going out the same day they're placed.

Frequently Asked Questions

HFP-CPN11 includes a high-pressure fuel pump, a low-pressure fuel pump, a wiring harness, and a rubber grommet, giving you a complete replacement for both original pumps in one kit.

HFP-CPN11 replaces OE part numbers 8M0062770 and 8M0062771, covering Mercury outboard and sterndrive engines, Mercruiser inboard and sterndrive engines, and Mariner outboard engines. Use the vehicle compatibility tool on the product page to confirm fitment for your specific model and year.

HFP-CPN11 is sold as a complete dual-pump kit because these systems rely on both pumps working together. Replacing only the failed pump often leaves a second, similarly worn pump in place to fail soon after, so the kit is built to close that gap.

Yes. HFP-CPN11 is fully compatible with ethanol-blended fuels, helping prevent the corrosion and premature failure that ethanol exposure can cause in pumps not built to handle it.

HFP-CPN11 is backed by QFS's industry-leading lifetime warranty covering defects in workmanship and materials for the original purchaser. Natural aging, debris accumulation, and improper installation are not covered, and fuel filters, strainers, and rubber components are treated as maintenance items with limited wear coverage.
