Sierra 18-7983-2 Fuel / Water Separator Bonus Pack
Sierra 18-7983-2 Fuel / Water Separator Bonus Pack — Product description
Keep your boat's engine running smoothly on every outing with a reliable fuel water separator designed for marine enthusiasts. Water contamination in gasoline is a common headache for boaters, leading to rough idling, hesitation, or even complete breakdowns far from shore. This bonus pack steps in as your first line of defense, tackling emulsified water and tiny contaminants before they reach your fuel injection system.
Superior Filtration for Peace of Mind
Engineered with precision, this separator captures over 98.8% of emulsified water mixed in your fuel, ensuring cleaner gasoline flows to your inboard or outboard motor. The 10-micron filter media excels at trapping particles down to that size with more than 90% efficiency, protecting sensitive components from wear and corrosion. Even high-performance engines demanding serious fuel volume get what they need, thanks to a robust 90 GPH flow rate that keeps up without restriction.
Whether you're cruising lakes, tackling offshore waves, or fishing all day, this setup minimizes downtime and extends engine life. Boaters often report fewer filter clogs and steadier performance after switching to advanced filtration like this—real-world reliability that beats basic inline filters.
Complete Kit for Easy Setup
Everything you need arrives in one convenient bonus pack: a sturdy mounting bracket for secure installation, the high-efficiency filter, and two brass pipe plugs (one 3/8-inch and one 1/4-inch) for customizing your plumbing. These corrosion-resistant plugs seal connections tightly, preventing leaks in harsh saltwater environments.
Installation is straightforward for DIYers familiar with basic fuel line work. Mount the bracket in a dry, accessible spot near your fuel tank or pump, connect the lines with the provided plugs, and prime the system. Always work in a well-ventilated area, away from sparks, and use marine-grade fuel line for best results.
Maintenance Made Simple
Regular checks keep this system performing at its peak. Inspect the filter element every 100 hours of operation or seasonally, whichever comes first. A quick visual for discoloration or debris tells you when to swap it out—typically lasting a full season under normal use. Drain any accumulated water from the bowl periodically to maintain efficiency, and replace plugs if threads show wear. This proactive routine prevents surprises and safeguards your investment.
Why Boat Owners Trust This Filtration Solution
In the marine world, where fuel quality varies from dock to dock, a dependable separator isn't optional—it's essential. This pack stands out for its balance of high flow, fine filtration, and durable construction, outperforming many stock options. It's particularly valued by owners of fuel-injected outboards and inboards prone to water ingress from condensation or bad gas. Pair it with fresh fuel stabilizers for year-round protection, and you'll notice the difference in throttle response and starting ease.
