Sierra 18-8149 High Capacity Fuel Water Separating Filter, Replaces Volvo 3847644, for Volvo Penta 2003/AQD2B/MD Series

The Sierra 18-8149 is a high capacity fuel water separating filter built for gasoline marine engines that use a side-by-side fuel pump setup. Rated at 10 micron, it removes over 99.8% of emulsified water from gasoline and is over 90% efficient at removing particles as small as 10 micron, while flowing at 90 gallons per hour to keep fuel delivery steady even under heavy demand. Protecting sensitive fuel injection systems from water contamination and debris is critical on inboard, sterndrive, and outboard applications, and this filter is designed specifically to guard against that damage.

The filter is constructed with an aluminum outer housing for durability in a marine engine environment. It fits most gasoline applications equipped with an electric fuel pump and directly replaces Volvo 3847644. It is designed to work with Volvo Penta 2003, 2003B/T/TB, AQD2B, MD11C/D, MD17C/D, MD1B, MD2B, MD3B, MD5A/B/C, and MD7/B engines. Note that some height restrictions may occur when this filter is used together with the Sierra 18-7778 aluminum replacement fuel filter bracket (Volvo 3850861), so check clearance before installing with that bracket.
