FUEL LINE CONNECTOR, MERCURY 5/16″ BARB

The Dometic Sierra 18-8085 Fuel Line Connector is a marine-grade female quick-connect fitting designed for use with Mercury®, Mariner®, and select Yamaha® outboard engines. This connector is installed on the fuel line assembly, providing a secure and reliable connection to compatible tank fittings such as the Sierra 18-8077.

Constructed from durable, corrosion-resistant materials, the connector is engineered to withstand harsh marine environments while maintaining consistent fuel delivery. The clip-style quick-connect design allows for fast attachment and removal while ensuring a tight, leak-resistant seal. As the larger-diameter version of the 18-8075, this model supports increased fuel flow for applications requiring a 5/16″ fuel line, making it ideal for a wide range of marine setups.
