1. Technical Specifications

2. Key Features

• Instant Lock & Quick Disconnect: Spring-loaded locking slide sleeve enables smooth, one-handed push-to-connect engagement with automatic check-valve cutoff upon release.

• Ethanol & Saltwater Resistant Sealing: Premium internal elastomeric O-rings resist swelling, hardening, and fuel vapor permeation when exposed to ethanol blends and marine environments.

• Heavy-Duty Cast Alloy Body: Rugged metallic housing resists physical crushing, deck stomping, and vibration cracking far better than plastic alternatives.

• Precision CNC Machined Mating Bores: Critical pin receiver tolerances ensure an airtight seal with standard male fuel plugs (e.g., 6E5-24305-06 / 6Y1 series), completely preventing vacuum air leaks.

3. Compatible Models

Universally compatible with Yamaha and industry-standard 2-prong fuel line configurations:

• Yamaha 2-Stroke Series: 2HP to 250HP outboards (e.g., 9.9F, 15F, 25B, 30G, 40X, 60F, 70B, 85A, 90A, 115A, 150A, 200A, etc.)

4. Aftermarket & Brand Compatibility

• OEM Brand Fitment:

• Yamaha Marine: Designed for genuine Yamaha outboard portable fuel line and tank quick-disconnect circuits.

• PREMARINE Brand Aftermarket Replacement:

• PREMARINE Quality Standard: PREMARINE specializes in high-durability marine fuel lines, primer bulbs, and quick-connect fittings. This female fuel joint is manufactured with pressure-tested alloy bodies and high-recovery stainless steel springs.

• Direct OEM-Level Performance: Vacuum sealing retention, coupling cycle life, and pull-off strength meet or exceed OEM specifications, serving as the premier cost-effective choice for building fuel lines or replacing leaking connectors.

5. Common Symptoms & Troubleshooting

• Primer Bulb Fails to Get Hard / Engine Stalls at High Throttle (Air Leak):

• Cause: Hardened or worn internal O-rings allowing ambient air to be sucked into the fuel stream under fuel pump vacuum.

• Troubleshooting: Inspect the connection for fuel mist or air bubbling; replace the female joint if the seal is degraded.

• Difficult Coupling / Connector Pops Off Under Navigation:

• Cause: Corroded or seized locking sleeve spring, or salt crust buildup inside the locking pin recess.

• Troubleshooting: Flush with fresh water and lubricate; replace the connector if the internal spring has collapsed.

• Continuous Fuel Dripping When Disconnected:

• Cause: Internal check-valve poppet stuck open due to debris, fuel varnish, or a broken valve return spring.

• Troubleshooting: Inspect the valve poppet; replace the joint assembly immediately to eliminate fire hazards on board.
