Mercury – Quicksilver 8M2018790 Pump Suction Filter | Gen III Cool Fuel Module | Marine Filtration | 8M2018790

Overview

If you’ve spent enough time on the water, you know that a smooth-running engine is never an accident. It’s the result of little things being done right—quiet components working behind the scenes to keep your day trouble-free. The Quicksilver 8M2018790 Pump Suction Filter is one of those parts. You don’t see it, you don’t think about it often, but you sure feel the difference when it’s doing its job. There’s a certain peace of mind that comes from knowing your fuel system is clean and steady, especially when you’re miles from the dock and relying on every bit of engine performance.

Performance & Practical Benefits

You can always tell when your fuel delivery system is healthy—the engine fires on the first turn, throttle response feels crisp, and there’s a steady, confident pull when you bring the boat up on plane. This Mercury Marine part plays a big role in that feeling.

The Pump Suction Filter sits at the heart of the fuel system’s first line of defense. By capturing debris, varnish flakes, and microscopic contaminants, it protects your fuel pump and injectors from the kind of slow-building restrictions that rob power and fuel economy. The flow it maintains is smooth and predictable, reducing the strain on downstream components. You’ll notice steadier idle performance, fewer hiccups at mid-range, and a generally tighter, quieter feel throughout the throttle range.

Marine environments are tough—heat, moisture, vibration, and unstable fuel quality all work against your engine. This filter is engineered to handle all of it without collapsing, clogging prematurely, or breaking down under pressure. Once installed, it simply does its job, keeping your fuel system cleaner and your engine happier.

Why Buy OEM

For something as critical as fuel filtration, OEM isn’t just recommended—it’s essential. Mercury’s engineering team tests every component against real-world conditions, from rough water pounding to long hours of continuous operation. Aftermarket filters might look similar, but they rarely match the exact flow rates and tolerances your system was designed around. With a genuine Mercury Marine part, you’ll get consistent performance, less maintenance guesswork, and the confidence that your fuel system is protected the way it should be.
