Sierra 18-7919 Replacement Fuel/Water Separtor Element

Enhance Your Marine Engine Performance with Sierra 18-7919

In the harsh marine environment, where moisture and contaminants lurk in every tank of fuel, a dependable fuel/water separator is your engine's first line of defense. The Sierra 18-7919 replacement element steps up to the challenge, designed specifically to capture water and debris while allowing easy drainage to prolong filter life. Boat owners trust this precision-engineered part for its ability to keep fuel clean and engines running smoothly, preventing costly corrosion, injector clogs, and performance hiccups that plague outboard and inboard setups.

Unlike basic filters that simply block particles, this element integrates advanced separation technology. It coalesces tiny water droplets into larger ones that settle at the bottom, ready for quick manual drain-off. This proactive approach minimizes downtime and maximizes reliability during long hauls or weekend cruises.

Smart Bowl Options for Every Installation

Pairing the Sierra 18-7919 with the right bowl ensures compliance and optimal function. For outboard motors and above-deck applications, opt for AquaVue clear bowls. Their transparent design lets you visually monitor water accumulation and fuel clarity at a glance—no guesswork needed. Spot issues early, drain effortlessly, and maintain peak efficiency.

Below deck, where safety regulations reign supreme, switch to the metal bowl collection. These flame-resistant units meet U.S. Coast Guard (USCG) standards, providing robust protection against fire hazards while housing the same high-performance element. Whether retrofitting an older vessel or upgrading a new one, these bowls deliver versatility without compromising safety or performance.

Proven Compatibility Across Popular Marine Engines

Engineered as a direct-fit replacement, the Sierra 18-7919 slots seamlessly into a range of popular fuel filter assemblies. It's a go-to choice for Mercury outboards, suiting models with 10-micron filtration needs, and works reliably in systems from other leading brands like OMC and Yamaha equivalents. Always cross-reference your OEM part number to confirm fitment, but marine mechanics rave about its OEM-level quality at a fraction of the cost.

• Ideal for 4-stroke outboards up to V8 configurations
• Handles high-flow demands in sterndrive and inboard applications
• Resists ethanol-blended fuels common in modern marinas

Installation and Maintenance Made Simple

Swapping in the Sierra 18-7919 takes minutes with basic tools. Shut off fuel supply, depressurize the line, unscrew the old element, and thread in the new one by hand—torque to spec if needed. Prime the system, check for leaks, and you're back on the water. Pro tip: Inspect the O-rings and seals during replacement to avoid future headaches.

For longevity, drain water weekly or after every 50 hours of operation, especially in humid climates or after refueling from questionable sources. Signs it's time for a new element include sluggish acceleration, rough idling, or visible water in the bowl. Regular upkeep with this filter extends service intervals, saving you time and money at the dock.

Why Sierra Stands Out in Marine Aftermarket Parts

Sierra's reputation for durable, no-fail components shines through in the 18-7919. Crafted with marine-grade media that traps even sub-10-micron particles, it outperforms generics that clog prematurely. Boaters report fewer breakdowns and cleaner carbs/injectors, translating to more time enjoying the water and less troubleshooting. Invest in reliability that matches or exceeds factory specs.
