Sierra 18-79915 79915 Fuel/Water Separator Kit W/Collection Bowl Product Description

Enhance Your Marine Engine's Reliability with Advanced Water Separation

Keeping water out of your boat's fuel system is crucial for preventing corrosion, injector damage, and unexpected breakdowns on the water. This fuel/water separator kit stands out by actively draining water from the filter media, significantly extending its service life and ensuring smoother operation during long outings or rough seas.

Designed for marine enthusiasts who demand durability, the kit includes high-quality elements that capture contaminants and moisture before they reach your engine. Whether you're running an outboard motor or a stern drive, integrating this separator means fewer filter changes and more time enjoying the ride.

Choose the Right Bowl for Your Installation

  • AquaVue Clear Bowls: Ideal for outboard engines and above-deck setups, these transparent bowls let you visually inspect water accumulation at a glance. Spot issues early and drain effortlessly without tools, perfect for quick maintenance during fishing trips or weekend cruises.
  • Metal Bowl Collection: Engineered for below-deck applications, these flame-resistant metal bowls meet stringent USCG regulations. They provide robust protection in enclosed engine compartments, safeguarding against fire hazards while efficiently collecting water and debris.

Selecting the appropriate bowl ensures compliance and optimal performance tailored to your boat's configuration, reducing downtime and enhancing safety.

Long-Term Benefits and Easy Maintenance Routines

Investing in this kit translates to tangible gains: cleaner fuel delivery leads to better combustion efficiency, improved throttle response, and reduced emissions. Boat owners report fewer hesitation issues and extended engine longevity, especially in humid coastal environments where water contamination is common.

Maintenance is straightforward—regularly check and drain the bowl to keep the system primed. The self-venting design minimizes air locks, making priming quick after filter swaps. Pair it with routine fuel polishing for peak performance, and you'll notice the difference in how your engine starts and runs.

Pro Tips for Seamless Installation and Troubleshooting

Begin by shutting off fuel supply and relieving pressure. Mount the unit in line with fuel flow, ensuring easy access to the drain valve. Use marine-grade hoses and clamps to avoid leaks. For stubborn water buildup, a gentle tap on the bowl can dislodge trapped droplets without disassembly.

Common pitfalls like improper orientation or overlooked O-rings are avoided with the included hardware. Test the system post-install by running the engine at idle and monitoring for steady flow—peace of mind starts here.

Real-World Scenarios Where It Shines

Picture this: You're mid-offshore tournament, waves kicking up spray, and fuel quality is your last worry thanks to proactive water separation. Or during winter storage, when condensation forms—drain it away to prevent ethanol-related gelling come spring. Saltwater anglers and offshore racers alike trust this setup for its proven track record in demanding conditions.
