Sierra 18-7094 Needle & Seat Assembly, Replaces OMC 396522 & 379313, for Johnson/Evinrude Outboard Engines 1.5-300 HP

The Sierra 18-7094 Needle & Seat Assembly is a carburetor fuel inlet replacement part built for select Johnson/Evinrude outboard engines. The needle and seat regulates fuel flow into the carburetor float bowl, sealing off fuel supply as the float rises to prevent flooding and ensuring consistent fuel metering for reliable engine performance. This assembly is designed as a direct equivalent to the original equipment part it replaces, meeting or exceeding original specifications.

This part is intended for select Johnson/Evinrude outboard engines ranging from 1.5 HP through 300 HP, covering a wide span of small and mid-size to high-horsepower outboard motors. Because carburetor needle and seat fitment varies by engine model and production year even within the same horsepower rating, buyers should confirm compatibility with their specific engine before ordering.
