This male fuel connector is specifically designed for the fuel systems of Mercury/Mariner outboard engines. It installs on the outlet of a portable fuel tank and serves as the quick-connect point for the engine’s fuel hose. With its bayonet-style design, the connector allows the fuel line to “snap” on easily for a secure connection and to be disconnected quickly when needed, without fuel spillage.
The male fitting has a standard threaded end that screws tightly into the tank’s port (most Mercury/Mariner portable tanks have a plastic threaded receptacle of the correct size). Its construction ensures a reliable seal – once the female connector on the fuel line is attached, the coupling becomes leak-proof, preventing any fuel leakage or air ingress. This guarantees steady fuel delivery to your motor without interruptions.
Made from high-quality materials, this connector is built to withstand prolonged exposure to gasoline, oil, and the marine environment. The metal threading provides a strong attachment to the tank, while the connector body is durable and wear-resistant. This fitting is standard for most Mercury/Mariner models and is ideal as a replacement for a worn or damaged connector – restoring the safety and reliability of your fuel system.
- For Mercury/Mariner Tanks: Compatible with OEM Mercury/Mariner portable fuel tanks and engine fuel lines – offers original fit and proper function.
- Replacement or Upgrade: Useful as a spare or replacement part if your old connector is worn out, or when equipping an additional fuel tank in your system.
- Safe Disconnect: When the fuel hose is unplugged, an integrated valve (if present) retains fuel in the tank, preventing spills and air entry into the line.
- Maintenance: It’s recommended to occasionally clean and inspect the O-ring/seal for optimal performance. With proper use, this connector provides years of reliable service.
By using this male tank connector, you ensure a secure fuel system connection so your Mercury/Mariner engine can run smoothly and safely.
