Mercury – Quicksilver Fuel Line Connector | Fuel System Component | Brass and Composite | 22831Q3

Overview

If you run an older Mercury or Mariner outboard, you know how much the small things matter. The Mercury Marine 22831Q3 Quicksilver Fuel Line Connector is one of those details that makes your setup run right. It’s designed for vintage TwoStroke engines built in 1971 or earlier, giving you a tight, dependable connection between the fuel tank and the motor. The twist-lock fitting snaps in securely and stays sealed, keeping air out and fuel flowing. It’s made from solid brass and durable composite, built to handle fuel, salt, and time — just like the rest of your Mercury gear.

Key Features

• Purpose: Creates a solid, leak-free link between your portable fuel tank and engine.
• Build: Made with marine-grade brass and reinforced composite for strength and corrosion resistance.
• Design: Twist-lock connector offers an easy, firm fit and quick release without drips or leaks.
• Performance: Keeps steady fuel flow for smooth starts and consistent throttle response.
• Compatibility: Fits Mercury and Mariner TwoStroke outboards (1971 and older) — not for 3.9–9.8HP models.
• Tip: When installing, check your fuel line and primer bulb; replacing them at the same time ensures a clean, sealed system.

Engine & Boat Compatibility

• Made for 1971 and older Mercury and Mariner TwoStroke outboards.
• Does not fit 3.9–9.8HP engines.
• Great choice for classic aluminum runabouts, small fishing boats, and restored vintage rigs.
• Works reliably in both freshwater and saltwater conditions.

Performance & Real-World Benefits

This connector brings back the reliability your old outboard was known for. The twist-lock design clicks securely into place, so there’s no guessing — you’ll know it’s sealed when you hear that snap. It keeps fuel flowing evenly and air out of the system, preventing rough running or hard starts.

The brass and composite build resists corrosion and holds its shape through years of use. Once installed, it becomes one of those “set it and forget it” parts — working quietly every time you squeeze the primer bulb or pull the starter.

Why Go With OEM

With vintage engines, fitment really matters. The Quicksilver 22831Q3 is the real deal — a genuine Mercury Marine part built to match the original connector’s specs perfectly. Cheaper aftermarket fittings often look close but don’t quite seal or hold under pressure. That’s when air leaks start and fuel delivery becomes inconsistent.

Mercury’s OEM connector is made for the environment your engine lives in: wet, salty, and full of vibration. It threads and locks in just right, giving you dependable fuel flow and the confidence that your motor will start and run like it’s meant to.
