Sierra 18-7712 Inline Fuel Filter for Nissan/Tohatsu Outboards, Replaces 369022300M

The Sierra 18-7712 is a compact inline fuel filter engineered for small outboard engines, designed to trap contaminants before they reach the carburetor and protect the fuel system from debris. It is built as a direct replacement for OEM number 369022300M and installs under the cowl on the outboard engine, in the fuel line ahead of the carburetor.

This filter fits 2-stroke outboards rated 5 HP thru 9.8 HP and 4-stroke outboards rated 4 HP thru 30 HP, covering a wide range of small outboard engines on Nissan/Tohatsu-based fuel systems. The filter element provides 74 micron filtration, catching sediment, rust, and debris that can clog jets or damage the carburetor over time. Its housing uses a metal outer construction for durability in the marine engine compartment.

The 18-7712 is also cross-referenced to Mercury Marine 35-16248 and Honda 16910-GB2-005, so it serves as a compatible replacement across those brands as well as its primary fitment. Each package includes one inline fuel filter, ready to install as routine maintenance or as a replacement for a clogged or aging filter. At just 0.02 pounds, it is a lightweight, low-cost component that helps keep an outboard's fuel system running clean.
