Troubleshooting & FAQ
What engines does this fuel connector fit?
This connector is designed for a variety of Johnson/Evinrude outboards, generally from 25 HP to 140 HP, that require a male bayonet connector for a 5/16" (8 mm) fuel line. It cross-references with OEM parts 174508, 173247, and 775640.
How do I confirm if this is the right part for my motor?
The best method is to compare the part number stamped on your old connector to the OEM numbers listed (174508, 173247, 775640). Additionally, verify that your fuel line is 5/16" and that the images match your existing part.
What are common signs of a failing fuel connector?
Symptoms of a bad connector include fuel leaks, difficulty starting the engine, stalling at idle, and a noticeable smell of gasoline around the connection point. Cracks, brittleness, or a loose fit are also clear indicators that a replacement is needed.
Is this a male or female connector?
This is a male connector, designed to fit into the female receptacle on the engine or fuel tank side.
Can I use this with ethanol-blended fuel?
This connector is designed for standard gasoline. While it may tolerate modern ethanol blends (like E10), it is always best practice to use materials specifically rated for high-ethanol content fuels if you frequently use them.
How often should fuel line connectors be inspected?
It is good practice to inspect all fuel system components, including connectors, at the beginning of each boating season or annually. Replace them immediately if you notice any signs of wear, damage, or leakage.
