<h3>Sierra: Six Decades of Marine Aftermarket Excellence</h3><p><strong>Sierra</strong> has spent nearly 60 years earning its reputation as one of the most trusted names in the marine aftermarket industry. Originally focused on engine and drive components for boats, the brand has grown into a comprehensive source for nearly everything a boater needs to keep their vessel running at its best — from precision instrumentation to complete engine rebuild hardware.</p><p>Now operating as a brand of Dometic, Sierra manages global aftermarket distribution from a 300,000 sq. ft. facility in Litchfield, Illinois. The Sierra brand today encompasses not only its flagship marine parts line but also well-established marine names like Shields and Moeller, offering boaters a broader catalog than ever before. Whether you own an outboard, inboard, or sterndrive, Sierra's engineering team designs products to meet or exceed OEM specifications.</p><h3>Precision Instrumentation You Can Trust on the Water</h3><p>One of Sierra's most recognized product areas is its marine instrumentation lineup. The brand's <a href="/7570-sierra-gauge-set-1480">gauge sets</a> cover everything from classic analog instrument clusters to advanced digital multi-function displays. Sierra offers packages suited to outboards, sterndrives, and gasoline-powered inboards, with options ranging from coordinated analog kits in styles like Arctic, Eclipse, and Amega to modern touchscreen solutions like the R3 multi-function gauge. Features such as scratch-resistant domed glass lenses, silicone-dampened pointers, and perimeter backlighting make these instruments highly readable in all conditions.</p><p>Behind every accurate gauge reading is a properly calibrated sending circuit. Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> are a critical part of that chain, ensuring the signals from sensors and sending units are correctly interpreted by your instruments. These components are built to marine-grade standards to resist moisture, vibration, and corrosion — the realities of life on the water.</p><h3>Engine Internals Built to OEM Standards</h3><p>Sierra's history in marine power is perhaps best demonstrated by its deep catalog of engine components. The brand's <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> cover a wide range of outboard and inboard applications and are engineered to deliver reliable seals in the demanding thermal and chemical environment of a marine engine. For boaters performing seasonal overhauls, top-end rebuilds, or full engine restorations, Sierra gasket kits are a go-to resource trusted by professional marine technicians and DIY boaters alike.</p><h3>A Complete Marine Parts Partner</h3><p>Beyond instrumentation and engine internals, Sierra's catalog spans fuel systems, electrical supplies, steering components, shore power, and more — all covered by what the brand calls an industry-leading warranty. Sierra also maintains a comprehensive parts-finder tool that enables cross-referencing with OEM part numbers from major manufacturers including Mercury, Yamaha, Suzuki, Volvo Penta, and others, making it straightforward to find the right replacement part for virtually any application.</p>

Product Details

The Sierra 18-7951 is a 10-micron marine fuel water separator kit designed for below-deck installations where USCG flame-resistance requirements apply. Featuring an aluminum bracket head and a flame-resistant metal drain bowl, this kit allows accumulated water to be easily drained from the filter element to extend service life and protect your engine from water-contaminated fuel.

Key Features:

  • 10-Micron Filtration: Over 90% efficient at capturing particles as small as 10 microns, helping prevent damage to sensitive fuel injection systems
  • Metal Drain Bowl (18-7924): Flame-resistant metal collection bowl meets USCG regulations required for below-deck installations
  • Drainable Design: Water-in-fuel can be drained from the filter without removing the assembly, extending filter service life
  • 1/4" Port Connections: Aluminum bracket head (18-7853-1) with 1/4" NPT inlet/outlet ports
  • Spin-On Filter Element: Includes Sierra 18-7919 10-micron filter element for straightforward servicing
  • Designed for 2 & 4-Cycle Gasoline Engines: Suitable for outboard and inboard marine gasoline applications

Kit Contents:

  • 1 x 18-7919 10-Micron Fuel Water Separator Filter
  • 1 x 18-7853-1 Aluminum Mounting Bracket
  • 1 x 18-7924 Flame-Resistant Metal Drain Bowl
  • 2 x 18-4256 1/4" Pipe Plugs

Important Installation Note: USCG regulations require the use of a flame-resistant metal collection bowl for all below-deck fuel system installations. For outboard or above-deck use, the Sierra AquaVue™ clear bowl kit (18-7932-1) is an alternative option offering visual water-level inspection.

Sierra International has been a trusted name in marine engine and drive parts for over 50 years, engineering products to meet and exceed the demands of today's high-performance marine engines.

quick, easy, painless shopping and checkout. Great!

Easy to use website, great communication, and product was exactly as described.

The listed matching vehicles were a little vague, still a little uncertain if the part will fit, will have to find out for sure once it arrives

Ordered it Friday had it at my door on Wednesday! They also had the cheapest prices of all reputable sellers.

Took a little longer to ship out the item than expected. But other than that, great prices. Great checkout process. Will deal with again if I find something else that I want to buy for my G35.<br>Thanks! (order #: 9261)

I will see when I get my exhaust how it was
