Johnson fuel line connectors are a source of confusion for many, with some reporting issues with fuel connectors being too small for the engine side, while others have found them to work well without any leakage. The size of the connector varies depending on the engine's horsepower, and it is crucial to install the right size to avoid issues. Some sources suggest that older Johnson motors had the same connectors on both ends, while others recommend a 3/8 fuel line for Johnson motors. It is important to note that the fuel line size for marine-grade applications may differ from those used in automotive vehicles, with the former having a higher fire testing rate.

What You'll Learn
Johnson/Evinrude fuel line connectors are standard
The connectors are typically female, with a 2-prong clip, and are compatible with ethanol-blended fuels. They are known to work well with the fuel system, providing a secure fit and no leaks. However, some customers have reported issues with gas leaking during connection or when the gasket inside breaks, causing spillage.
The Johnson/Evinrude fuel line connectors are available from various brands, including Moeller Marine, West Marine, and HeuroFosh. They are commonly used for outboard connections and fuel tank sides, ensuring a proper seal when connected to a portable fuel tank.
It is important to note that there may be variations or different versions of the connectors, as some customers have experienced issues with the connector size not fitting their engine model. In such cases, it is recommended to verify the compatibility of the connector with the specific engine model.

Johnson/Evinrude fuel line connectors vary in size
For example, the Moeller Johnson/Evinrude Female Barb Fuel Line Engine Connector is designed for use with BRP (Johnson/Evinrude) outboard engines and has a 3/8" inner diameter. It attaches securely to the fuel hose on either the tank or engine side and features high-quality brass and aluminium fittings.

However, some customers have reported issues with leakage, particularly during connection or when the gasket inside breaks. It is worth noting that older Johnson/Evinrude motors may have different-sized fittings, and there may have been different versions of connectors prior to 1990. For instance, one customer with a 1989 Evinrude 8hp engine found that the standard Evinrude/Johnson fuel line connector was too small for the barb on the engine, and they had to use a Yamaha connector instead.
To avoid leakage and ensure the correct fit, it is recommended to check the specific requirements of your engine and purchase connectors from reputable sources that offer accurate product information and sizing details.
