Performance & Practical Benefits

Outboards run their best when the fuel running through them is clean and consistent. With the 8M0154753 filter, you’ll feel the difference in the way the engine settles into a steady idle, pulls smoothly through the midrange and responds instantly when you need quick throttle. The ten-micron element doesn’t just trap big debris—it captures the tiny particles that cause hesitation, roughness and long-term wear.

Water is the real enemy in any marine fuel system. This filter’s water-separating design helps keep moisture from slipping past and entering the engine, protecting injectors, pumps and internal components from unnecessary strain. And because it’s an inline filter, replacing it is quick and straightforward. You simply remove the old one, install the new element and get back on the water. No messy surprises and no complicated procedures—just a tight, clean replacement that restores confidence in your fuel line.
