Keeping your Suzuki on plane isn’t just about fresh fuel—you’ve got to seal every drop inside the system. The Suzuki Fuel Filter Seal 15415-93J10 is the small, no-nonsense O-ring that slides between your 15412-93J10 cartridge and the filter head on DF200-DF350A V-6 outboards. Molded from marine-grade nitrile rubber, it shrugs off ethanol blends, heat, and salt so fuel pressure stays rock-steady and air bubbles never reach the injectors.

Why swap it with every filter change?

• OEM precision fit. Designed to match the factory groove on DF200, DF225, DF250, DF300, and DF350A models for a leak-free seal.

• Fuel-resistant elastomer. Holds its shape after seasons of gas, oil, and UV exposure.

• Two-minute install. Roll out the tired ring, seat the new one—no sealant or special tools required.

• Performance insurance. Keeps the rail primed, preserves pump life, and maintains crisp throttle response.

Toss a spare in your onboard kit and treat it like a one-time gasket: new filter, new O-ring, guaranteed peace of mind all the way back to the dock.
