The DZFST.FI S3213 fuel water separator is engineered for marine use and matches multiple OEM numbers so you can swap it in quickly. It uses a three-layer synthetic filter media to capture particles and separate water, helping to reduce injector and pump wear while keeping combustion cleaner.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this filter protect my outboard on the water?\u003c\/h3\u003e\n\u003cp\u003eThe separator removes water and traps solid contaminants before they reach sensitive fuel system components. That lowers the risk of corrosion, injector clogging, and inconsistent engine operation without altering fuel flow characteristics when installed correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10-micron filtration rating catches fine particulates.\u003c\/li\u003e\n  \u003cli\u003eThree-layer synthetic fiber media enhances dirt-holding capacity.\u003c\/li\u003e\n  \u003cli\u003eWater-separating design sheds free water to protect pumps and injectors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my engine and which part numbers does it replace?\u003c\/h3\u003e\n\u003cp\u003eThis unit is a plug-and-play replacement compatible with many outboard setups; it’s matched to common OEM references to simplify ordering.
