Sierra 18-8069 Female Fuel Connector, 5/16 Inch, Replaces 22831Q3 - Mercury Outboard

The Sierra 18-8069 is a 5/16 inch female fuel connector built for Mercury outboard fuel line systems. It is the female half of a twist-lock fuel line coupling, designed to mate with the corresponding male connector to create a secure, leak-resistant seal at the fuel line disconnect point between the tank and the outboard motor. The connector is machined from brass for corrosion resistance and long service life in a marine fuel environment, with 5/16 inch NPT threading for connection to standard fuel line hose.

This female connector mates with the Sierra 18-80410-1 male connector to complete the fuel line coupling. It is a direct cross-reference replacement for several factory female fuel connectors used across a range of Mercury outboard motors, making it a straightforward swap when a factory connector is worn, cracked, or no longer sealing properly. Fitment covers Mercury 125 4-cyl. (1994 and up), 65 Jet (1994 and up), 75 3-cyl. (1987 and up), 80 Jet (1994 and up), and 90 3-cyl. (1987 and up) outboards.
