Mercury – Quicksilver Quick Disconnect Fuel Line Fitting | Fuel System Component | Brass and Composite | 13563Q7

Overview

Every boater knows that your engine’s only as reliable as the fuel system feeding it. The Mercury Marine 13563Q7 Quicksilver Quick Disconnect Fuel Line Fitting is one of those small but essential parts that keeps that connection solid and leak-free. Built for Mercury, Mariner, and Force outboards, this fitting connects your portable fuel tank to your motor with a clean, secure snap. It’s the kind of part you don’t think about often — and that’s the point. It just works, season after season, every time you fire up the engine.

Performance & Practical Benefits

This fitting feels solid the moment you connect it — no wiggle, no leaks, just a clean, tight fit. The double-seal design keeps fuel flowing smoothly and air out of the line, so your engine gets consistent pressure from idle to full throttle. The brass and composite materials resist corrosion, even after repeated exposure to ethanol-blended fuels and salt spray.

Replacing an old or worn connector with the 13563Q7 fitting helps eliminate fuel drips, soft fittings, or hard starts caused by air leaks. Once it’s in place, you can expect a steady, reliable connection every time you hook up your fuel line — no guesswork, no frustration.

Why Buy OEM

There are cheaper fittings on the market, but they rarely hold up the way a genuine Mercury Marine part does. The Quicksilver 13563Q7 is built to Mercury’s original engineering specs, meaning the threads, seals, and tolerances are exact. That perfect fit isn’t just convenience — it’s safety.

With OEM quality, you know your connection will stay tight under vibration, temperature swings, and daily use. It’s the kind of part that quietly earns your trust, season after season, simply by doing its job right.
