Sierra 18-7351 Fuel Pump Johnson/Evinrude 438562 Product Description
Why Your Outboard Needs a Reliable Fuel Pump Like the Sierra 18-7351
Nothing kills a day on the water faster than a sputtering engine starved for fuel. The Sierra 18-7351 steps in as a dependable replacement for Johnson/Evinrude OEM part 438562, engineered to restore smooth power delivery in demanding marine conditions. Boat enthusiasts know that fuel pumps endure constant vibration, corrosion from saltwater exposure, and the harsh effects of modern ethanol-blended fuels. This aftermarket gem matches original specs while offering enhanced durability, helping you avoid those frustrating breakdowns mid-lake.
Unlike stock pumps that degrade over time from diaphragm hardening or internal clogs, the Sierra design incorporates robust materials that resist wear. It's not just a part—it's peace of mind for weekend warriors and commercial operators alike, ensuring consistent fuel flow for optimal combustion and performance.
Key Features and Performance Advantages
- Precision Engineering: Direct OEM equivalent with exact fitment, no modifications required for seamless integration into your Johnson/Evinrude setup.
- Corrosion-Resistant Construction: Built with marine-grade components to battle humidity, salt, and fuel varnish buildup, extending service life in harsh environments.
- High-Volume Delivery: Maintains steady pressure for reliable starting, idling, and wide-open throttle, even under load.
- Easy Diaphragm Access: User-friendly design allows quick inspections and rebuilds, saving time during routine maintenance.
- Universal Pulse Fit: Compatible with diaphragm-style systems common in 2-stroke outboards, syncing perfectly with crankcase pulses.
Users report fewer vapor lock issues and improved throttle response after installation, making it a smart upgrade for aging engines prone to fuel starvation.
Perfect Fit for Johnson/Evinrude Engines
This fuel pump slots right into a range of classic Johnson/Evinrude powerheads, serving as the go-to replacement for part 438562. It's tailored for mid-range horsepower models where fuel delivery reliability is non-negotiable. Always cross-reference your engine's serial number to confirm, but mechanics swear by its plug-and-play reliability across compatible setups.
Simple Installation Steps
- Disconnect the fuel line and battery to safely depressurize the system.
- Remove the old pump by loosening mounting screws and detaching hoses—label them for easy reassembly.
- Transfer any fittings or pulse lines, then bolt on the Sierra 18-7351 using existing hardware.
- Prime the system with fresh fuel, check for leaks, and fire it up. Pro tip: Use inline filters to prevent debris from shortening its lifespan.
Most swaps take under an hour with basic tools, getting you back on the water without a tow.
Maximize Longevity: Maintenance Best Practices
To keep your new fuel pump humming season after season, prioritize ethanol-free fuel when possible—it's less aggressive on rubber components. Flush the system annually with a stabilizing additive to dissolve varnish. Watch for signs of trouble like hard starting or black smoke, which signal diaphragm wear. Pair it with a quality anti-siphon valve and fuel separator for bulletproof operation. Regular checks during winterization can spot issues early, preventing costly overhauls.
