Built from brass and specified for 1\/4\" NPT tank threads, the part is suitable for ethanol-blended fuels and designed to minimize vapor loss and leaks. It’s a straightforward hardware swap that restores a secure clip-style connection between tank and engine fuel lines.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this connector match Mercury and Yamaha fittings?\u003c\/h3\u003e\n\n\u003cp\u003eThe FO4409 uses the standard two-prong clip interface and 1\/4\" NPT tank thread common to many Mercury and Yamaha portable fuel systems since 1998. It reproduces the geometry and sealing behavior expected by those OE female connectors so the latch and flow align properly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with Mercury OE parts 22-13563A6, 22-13563Q7, 22-13563T7\u003c\/li\u003e\n  \u003cli\u003eWorks with Five Oceans female connector FO2900\u003c\/li\u003e\n  \u003cli\u003eStandard two-prong clip style for reliable engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4\" NPT tank thread fits most portable marine tanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fitting handle ethanol-blended fuel and prevent leaks?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the connector is brass with low-permeation materials where required, chosen to resist the swelling and degradation that can occur with ethanol blends.
