Performance & Practical Benefits

The 13563Q3 connector gives you a tight, confident fit every time you connect your fuel line — no leaks, no guesswork. Its dual-seal design keeps air out and fuel flowing smoothly, ensuring consistent pressure all the way to the carburetor or EFI system.

The brass and composite body holds up against vibration, temperature swings, and ethanol-blended fuels. It’s easy to install, and once it’s in place, you can count on steady performance whether you’re idling in the marina or running full throttle across open water. It’s the kind of part that disappears into the background — doing its job perfectly so you don’t have to think about it.

Why Buy OEM

Not all connectors are created equal. The Quicksilver 13563Q3 is a genuine Mercury Marine part, built to the same standards as the rest of your outboard. Its precision-machined fittings and high-grade seals mean a perfect fit that won’t leak or loosen. Aftermarket parts might look similar, but few hold up to Mercury’s testing or long-term marine exposure.

With OEM parts, you get the right connection every time — secure, clean, and ready to handle real-world boating conditions. It’s a simple upgrade that ensures your engine gets the consistent fuel flow it needs for reliable starts and strong performance.
