Sierra 18-8089 Fuel Connector (Engine End) - Replaces 3B2-70260-O, Fits 5-90HP 2-Stroke & TLDI Outboards

The Sierra 18-8089 is an engine-end fuel connector designed to join the fuel line to the engine on compatible outboard motors. It features metric threads and is sized for 5/16 inch fuel hose, providing a secure connection point in the fuel delivery system. This connector mates with the Sierra 18-8088 fitting to complete the engine-side fuel line connection, and it is packaged 10 to a package for shops and technicians who need to keep several on hand for service and repair work.

This part directly replaces OEM number 3B2-70260-O and fits 5-90HP 2-stroke and TLDI outboard models. Because it uses metric threads, it is built to the specification of the outboards it is designed for rather than a generic imperial fitting, so installers should confirm thread compatibility before use. The connector is finished in white and is compact in size, making it a straightforward, purpose-built replacement part for maintaining proper fuel flow at the engine connection point.
