- HFP-CPN1 is a complete dual-pump solution designed to replace OE # 855427A1, 855432A07, 855432A1, 855432A2, 855434A1, 880596T55, 881705A1, 888725T1, 889441T (High Pressure) and 855843, 8558432, 85698414, 855843-2, 855843-3, 8M0047624 (Low Pressure) in one kit
- Specifically engineered for Mercury EFI and Optimax outboards within the 0G960500 THRU 0T178499 serial range, providing a precision fit for the factory fuel system
- Comprehensive System Refresh: This kit includes the high-pressure pump (VST), the low-pressure lift pump, specialized rubber isolators to dampen vibration, and marine-grade hose clamps for a leak-proof installation
- Restores the entire fuel delivery cycle—the lift pump ensures the vapor separator tank remains full while the high-pressure pump maintains the atomization needed to resolve engine surging, bogging under load, and loss of top-end power
- Manufactured from advanced, ethanol-resistant materials, these pumps are built to withstand the corrosive effects of modern marine fuels, preventing the internal seizure and "heat-soak" failure common in high-heat engine bays
- Get back on the water with confidence – Guaranteed – As a US-based small business, we know that offshore reliability is everything. Backed by our lifetime warranty, we stand by our products and our community
