Performance & Practical Benefits

The 14360A78 Fuel Pump Kit is all about steady, predictable performance. Each component is engineered for precise fuel flow and pressure regulation, ensuring your outboard delivers clean acceleration and smooth idle. The materials resist ethanol corrosion and heat, keeping your system sealed and reliable through long days on the water.

Replacing a worn fuel pump doesn’t just fix hard starting — it restores efficiency, prevents flooding, and gives your engine the strong, even delivery it needs under load. Installation is straightforward, and with every part included, you’ll have everything you need to get back to dependable operation.

Why Buy OEM

Aftermarket kits might look similar, but they rarely meet the exact tolerances Mercury builds into its systems. The Mercury 14360A78 is a genuine OEM kit, designed for exact pressure output, flow rate, and fit. That precision is what keeps your engine running like it was designed to — no leaks, no over-fueling, no stumbles at mid-range RPM.

OEM means factory quality, real-world testing, and long-term durability. With Mercury, you’re not just getting replacement parts — you’re getting components that protect the performance and longevity of your entire fuel system.
