Performance & Practical Benefits

You’ll feel the difference immediately. The primer bulb firms up with clean, even pressure — no softness, no hesitation — giving you the clear indication that fuel is moving properly. From there, the hose routes easily through tight rigging spaces, bends around corners without collapsing, and resists kinks even when the boat hits chop or shifts weight unexpectedly. That flexibility supports a steady flow of fuel, which leads to easier starts, cleaner idle, and more consistent overall performance.

On warmer days, the gray heat-reflective outer coating helps keep the hose cooler, reducing vapor-lock risk during long runs or slow trolling sessions. The low-permeation hose also helps limit gasoline odors and slows evaporation — especially helpful if your boat spends time covered or stored indoors. Over time, the hose stays flexible instead of stiffening or cracking, and the primer bulb maintains its reliable firmness season after season. Altogether, you get a smoother, more dependable boating experience with fewer fuel-related surprises.

Why Buy OEM

When it comes to your fuel system, genuine Mercury Marine components make a difference you can feel. Every part of this assembly — from the hose material to the internal valves inside the primer bulb — is engineered specifically for the demands of marine use. Aftermarket products might look similar, but they rarely match Mercury’s long-term durability, priming consistency, or precise fit. Choosing OEM gives you dependable operation, proper fitment, and the peace of mind that your fuel system meets the same standards as your Mercury outboard. It’s the smart choice for boaters who want reliability over shortcuts.
