Performance & Practical Benefits

This connector delivers a clean, solid lock every time you snap it on. The 13563T7 connector uses a dual-seal design that prevents air leaks and fuel drips, keeping your engine’s fuel supply steady and reliable. The brass and composite construction resists corrosion and holds its shape under vibration, heat, and repeated use.

You’ll notice the difference right away — smoother starts, consistent fuel delivery, and fewer hassles at the dock. Once installed, it’s the kind of component that disappears into your setup, quietly doing its job trip after trip without needing attention.

Why Buy OEM

When it comes to fuel systems, precision matters. A poor-fitting connector can cause leaks, air intrusion, or pressure drops — problems that can ruin a day on the water. The Quicksilver 13563T7 is a genuine Mercury Marine part, built exactly to factory specifications. That means perfect fitment, durable materials, and long-term performance you can trust.

With OEM parts, you know your connection will hold up through salt, vibration, and ethanol-blended fuels. Mercury’s engineering ensures each piece is tested under real marine conditions, giving you confidence in every start. It’s a small part, but one that makes a big difference in how your boat runs.
