Sierra 18-99184 99184 Repalcement Racor Turbine Fuel Water Separator Filter, 30 Micron

Keep your marine engine running smoothly and reliably with the Sierra 18-99184 replacement filter for Racor Turbine Fuel Water Separator systems. This 30-micron filter is engineered to capture contaminants and water from diesel fuel, preventing costly damage to injectors, pumps, and other critical components. Boat owners trust it for its robust performance in harsh saltwater environments, where fuel quality can vary wildly due to condensation, algae growth, or poor storage.

Why Choose the Sierra 18-99184 for Your Vessel?

Unlike standard filters that merely strain fuel, this turbine-style separator uses centrifugal force combined with precise 30-micron filtration to spin out heavier water and debris. The result? Cleaner fuel delivery that extends engine life and reduces downtime during long cruises or commercial operations. Sierra's design meets or surpasses original equipment specifications, making it a smart upgrade for recreational boaters and professionals alike.

Standout Features for Effortless Maintenance

• Direct Racor Turbine Replacement: Perfectly compatible with FWS series filters, ensuring a seamless swap without modifications.
• Integrated Bail Handle: The clever top-end cap design with a built-in handle simplifies removal, even in tight engine compartments—say goodbye to frustrating slips and spills.
• Superior Media Quality: High-efficiency pleated elements trap tiny particles down to 30 microns while allowing optimal fuel flow, balancing protection and performance.
• Durable Construction: Built to withstand vibration, pressure surges, and corrosive marine conditions for longer service intervals.

How the Turbine Separation Process Works

Fuel enters the filter assembly and spins through the turbine wheel, forcing water droplets and sediments to the outer walls where gravity pulls them into the collection bowl. The clean, dry fuel then passes through the 30-micron element for final polishing. Regular inspection of the clear bowl lets you monitor water accumulation—essential in humid climates or after fueling from questionable sources. This proactive setup minimizes risks like fuel starvation or injector fouling that plague unfiltered systems.

Installation and Service Tips for Peak Performance

Swapping in the Sierra 18-99184 is straightforward: Drain the old bowl, unscrew the filter canister using the bail handle, lubricate the O-ring with clean fuel, and hand-tighten the new unit to spec. Always replace the O-ring to prevent leaks. For best results, service every 500-1000 hours or when the bowl fills halfway, whichever comes first. Pair it with a quality primer bulb to bleed air efficiently post-install.

Real-World Benefits Backed by Boaters

Owners report fewer service calls, smoother idling, and better fuel economy after upgrading. In one case, a fishing charter captain avoided a mid-trip breakdown by spotting water buildup early. It's not just a filter—it's peace of mind on the water, especially when crossing bays or running offshore where rescue isn't immediate.
