Sierra 18-7919 Fuel Water Separator Filter is a 10-micron spin-on replacement filter designed to help protect marine fuel systems from water and debris. Built for inboard, sterndrive, and outboard applications, this Sierra fuel filter helps maintain clean fuel flow and supports reliable engine performance in harsh marine conditions. Its water-separating design allows accumulated water to be drained from the system, helping extend service life and reduce the risk of contamination-related issues.

Key Features

  • 10-Micron Filtration: Helps remove fine particles and water that can damage fuel injection components and reduce engine efficiency.
  • Spin-On Replacement Design: Features an 11/16 in.-16 thread for straightforward installation on compatible Sierra fuel/water separator assemblies.
  • Marine Application Ready: Designed for use in demanding boating environments, with support for systems flowing up to 90 GPH.

Boat owners choose Sierra replacement filters for dependable fit, solid filtration performance, and broad marine compatibility. The Sierra 18-7919 is a practical maintenance item for keeping fuel cleaner during routine service, seasonal prep, or replacement of a clogged separator. For above-deck and outboard installations, it is commonly used with Sierra AquaVue clear bowl setups that make water inspection easier.

For below-deck installations, Sierra specifies the use of a flame-resistant metal bowl to meet USCG requirements. Always confirm fitment with your engine or separator assembly before ordering, especially when cross-referencing Mercury, Quicksilver, Racor, or Yamaha applications.
