Five Oceans 1/4 in NPT Fuel Tank Connector — Brass 2-Prong for OMC/Johnson/Evinrude, Low-Permeation

This compact brass connector replaces worn or leaking tank ends and restores a dependable fuel line interface for outboard engines. Built to fit standard 1/4" NPT tank threads and the classic two-prong clip style used by OMC/Johnson/Evinrude systems, the FO4407 is made from low-permeation materials suited for ethanol-blended fuels. It’s a direct, serviceable part for boaters who need a reliable mechanical connection without modifying the fuel system.

How does the FO4407 ensure a leak-resistant connection?

The connector uses machined brass threads and a two-prong clip interface to lock into the corresponding female fitting, reducing play and minimizing vapor loss. Its low-permeation design helps limit fuel evaporation when used with ethanol blends, and brass offers corrosion resistance in marine environments.

• Precision 1/4" NPT brass threads for tight sealing
• Two-prong clip style for firm mechanical engagement
• Low-permeation materials to lower vapor escape
• Compatible with ethanol-blended fuels commonly used today

Will this connector work with my OMC/Johnson/Evinrude tank and hoses?

The FO4407 is engineered to match original equipment (OE) OMC/Johnson/Evinrude female fittings and fits Five Oceans female connectors such as FO2152 and FO2885. If your portable tank uses a 1/4" NPT female thread and the two-prong clip receiver, this male connector will mate directly without adapters.

• Direct-fit for original OMC/Johnson/Evinrude female fittings
• Fits Five Oceans FO2152 and FO2885 female connectors
• 1/4" NPT thread compatible with most portable tanks
• Simple swap-in replacement—no special tools required

How easy is installation and what should I replace at the same time?

Installation is straightforward: remove the old fitting, wrap threads if required, and thread in the FO4407 until the two-prong clip aligns with the mating female receptacle. Five Oceans recommends replacing aged fuel lines and primer bulbs when changing the tank connector to ensure the entire fuel path is sound and leak-free.

• Hand-tighten then secure to manufacturer torque recommendations
• Inspect and replace worn fuel hose and primer bulbs simultaneously
• Use thread sealant suited for fuel systems if specified
• Check for leaks before operation

What environments and fuels is this connector suitable for?

Designed for marine applications, the FO4407 tolerates the damp, salty conditions common to boating when maintained properly. Its materials are compatible with modern gasoline blends that include ethanol, and the brass construction resists corrosion compared with lower-grade metals.

• Intended for boats and portable marine tanks
• Works with ethanol-blended gasoline
• Brass body for increased corrosion resistance
• Not a replacement for damaged tanks—use as a connector only

Who this is for: The Five Oceans FO4407 is made for boat owners, mariners, and marine technicians who need a reliable OE-compatible fuel tank connection for OMC/Johnson/Evinrude systems. It’s ideal if you’re replacing a worn male tank fitting, upgrading to a low-permeation part for ethanol fuels, or restoring a portable tank’s fuel interface while keeping installation simple and reversible.
