This strategic expansion brought established marine brands like Shields and Moeller under the Sierra umbrella, creating a one-stop resource for marine maintenance and replacement parts. The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture. Their warranty coverage extends beyond simple part replacement—it includes shop labor, haul-out fees, towing charges, and related incidental costs should a warrantied part fail. This comprehensive protection reflects the company's confidence in their manufacturing processes and quality control standards. For boat owners facing repairs far from shore or mechanics working on customer vessels, this peace of mind is invaluable. Whether you're maintaining an outboard motor, rebuilding an inboard engine, or upgrading your boat's instrumentation, Sierra's decades of marine industry experience and commitment to quality make them a reliable choice for keeping your vessel running at peak performance.</p>

Product Details

The Sierra 118-7929 is a marine-grade fuel filter and water separator assembly designed for inboard and below-deck installations. Built to protect carbureted and fuel-injected engines from the harmful effects of water contamination and particulate debris, this assembly is an essential part of any complete marine fuel system.

Ethanol-blended fuels absorb more water and loosen more particulates than standard gasoline, making proper filtration critical for engine longevity and performance. The Sierra 118-7929 addresses this directly with a 10 micron filter element that is over 90% efficient at removing contaminants, while eliminating over 99% of emulsified water from fuel before it reaches the engine.

Key Features:

  • 10 Micron filtration — over 90% efficient at capturing particles as small as 10 microns
  • Removes over 99% of emulsified water from gasoline, protecting pumps, injectors, and carburetors
  • 90 GPH fuel flow rate — delivers adequate fuel flow even for high-horsepower engines
  • Metal collection bowl — meets ABYC and USCG heat tests; required for below-deck and engine room use per USCG regulations
  • Drainable bowl design — allows collected water to be purged to extend filter service life
  • Independently tested to JIS, SAE J1839/J905, and ISO 4548-12 standards
  • Replaces Mercury 35-809100, Racor B32020MAM, and Mallory 9-37883

What's Included:

  • Sierra 18-7919 10 Micron Fuel Water Separator Filter element
  • Sierra 18-7924 Metal Collection Bowl

This assembly is ideal for inboard engines and any below-deck installation where USCG-compliant, flame-resistant metal bowl housings are required. Cross-references OEM part numbers Mercury 35-809100, Racor B32020MAM, and Mallory 9-37883.
