FUEL LINE CONNECTOR, MERCURY 3/8″ BARB

The Dometic Sierra 18-80410 Fuel Line Connector (also referenced as 18-80410-1 or 18-800410) is a marine-grade female quick-connect fitting designed specifically for smaller outboard engines. This connector is used on the fuel line assembly, providing a secure and reliable connection to compatible engine fuel inlets.

Unlike standard connectors such as the 18-8075 and 18-8085, this model is designed for specific small-engine applications, making it essential to match the correct connector type to the engine. Constructed from durable, corrosion-resistant materials, it is built to withstand harsh marine environments while ensuring consistent fuel delivery. The quick-connect design allows for easy attachment and removal, making it ideal for portable fuel systems and routine maintenance.
