Mercury – Fuel Line Assembly | Fuel System | Gray Low-Permeation Hose | 8M0082290

Overview

There’s a certain ease that comes from knowing your fuel system will behave exactly the way it should. It starts with that familiar squeeze of the primer bulb — the smooth, steady pressure that lets you know fuel is moving cleanly toward the engine. The Mercury Fuel Line Assembly 8M0082290 is built for boaters who appreciate that dependable feeling. Whether you’re slipping out early for a quiet morning drift or cruising back through an afternoon breeze, this assembly keeps fuel flowing steady and reliable so you can focus on the water, not the line feeding your engine.

Performance & Practical Benefits

You’ll notice the quality the moment you prime it. The bulb firms up with that clean, confident pressure that reassures you fuel is moving exactly how it should. The hose routes easily through rigging spaces, bends smoothly around corners, and resists collapsing or kinking even when the boat meets chop or shifts weight. That flexibility helps maintain steady fuel flow, leading to easier starts, smoother idle, and more consistent performance on the water.

On hot days, the gray exterior coating helps reflect heat, keeping the fuel line cooler and reducing the chance of vapor lock during long runs or slow trolling. The low-permeation hose also helps cut down on gasoline odor and slows fuel evaporation — especially useful if the boat spends time under a cover or in storage. Over the long term, the hose stays supple instead of stiffening or cracking, and the primer bulb maintains its reliable squeeze season after season. Together, these details add up to fewer interruptions and a smoother, more enjoyable time on the water.

Why Buy OEM

Fuel delivery isn’t something to compromise on. Mercury Marine designs each component of this assembly — from the hose blend to the internal valves inside the primer bulb — specifically for marine use. Aftermarket versions might look similar, but they rarely match Mercury’s durability, priming strength, or long-term consistency. Choosing OEM ensures proper fit, dependable operation, and the peace of mind that your fuel system meets the same standards as your engine. It’s the practical choice for boaters who value reliability above all else.
