Mercury – Fuel Line Assembly for Mercury and Mariner Outboards | Fuel System | Low-Permeation Gray Hose | 8M0061894

Overview
If you have ever stood at the ramp squeezing a tired old primer bulb while your outboard refuses to wake up, you know how quickly a fuel line can ruin a good morning. When the line is right, you barely think about it. A few squeezes, the engine lights, and you are backing away from the dock with a grin. The Mercury 8M0061894 Fuel Line Assembly is built for that kind of start. It is a Mercury Marine part you install once and then quietly trust, season after season, whether you are cruising the shoreline at sunset or pushing hard to beat the weather back in.

Performance & Practical Benefits
You feel this fuel line working every time you prime the system and the engine fires without drama. The primer bulb on part number 8M0061894 feels solid in your hand, not spongy or dry. A few squeezes and you can tell fuel is moving, line filling, and the engine is ready to go. Starts are quicker, and there is less of that uneasy pause while everyone on board waits to see if the motor will catch.

Once you are underway, the low permeation hose helps keep the fuel where it belongs. You will notice fewer fuel smells in the cockpit and a more consistent, steady supply to the engine. The gray outer layer reflects sunlight, keeping temperatures in check and reducing vapor lock on hot afternoons when the tank bakes in the stern. The quick connectors at both ends snap in with a clean, secure feel that is tight and reassuring. You can swap tanks or disconnect for storage without wrestling with stubborn fittings or wondering if something will leak when the sea gets choppy.

Why Buy OEM
Fuel delivery is not a place to gamble with guesswork parts. A genuine Mercury Marine part like the 8M0061894 Fuel Line Assembly is designed around the specific connectors, fuel demands, and conditions that Mercury and Mariner outboards see every day. The hose material, bulb design, and fittings are chosen to handle marine fuel, vibration, and temperature swings, not just look close enough on a parts wall.

Could you build a fuel line from bulk hose and random connectors? Probably. But you will spend more time matching parts and still wonder if something is slightly off. With this Mercury Marine part, the engineering is already done. You get a clean, matched assembly that simply works, which usually ends up cheaper than chasing fuel issues later. If a friend at the marina asked what fuel line to run with a portable Mercury tank, this is the kind of setup you would recommend without thinking twice.
