10 Micron Replacement Filter Element for Fuel Separator (Yamaha/Mercury)
This replacement filter element (code 01884) is intended to keep your Mercury/Yamaha fuel separator in optimal condition. Over time, the paper filter media inside the separator gradually fills up with trapped particles and may become saturated with absorbed water. This reduces the filtration efficiency and fuel flow. Instead of replacing the entire filter, it’s sufficient to swap out the internal filter element for a new one – a process that is more economical and eco-friendly. This 10-micron element is a genuine EVAL product, ensuring perfect fit and performance. It’s compatible with several separator models (including codes 01836-1, 01866-1, 01836-2, 01866-2), covering a wide range of Mercury and Yamaha engine applications. The replacement itself is straightforward: after relieving fuel pressure or stopping fuel flow, remove the old cartridge as per the manufacturer’s instructions (typically by unscrewing the filter’s cap or bowl), inspect and clean the interior of any sludge, then insert the new element, ensuring proper sealing with the provided O-rings or gaskets. After reassembly, make sure everything is dry and prime the fuel system, checking for leaks. The new filter element will restore the flow rate and water-catching ability of your separator, safeguarding the engine from the ill effects of bad fuel.
- Best Practice: Mercury/Yamaha-type fuel separators usually have a recommended interval for replacing the filter element – for example, every 50-100 engine hours or once a year. Adhering to these intervals, or even replacing more frequently when using fuel of questionable quality, will save you from troubles on the water. Always keep at least one spare 10 µm element (like this one) in stock so you can respond quickly when needed. Dispose of used elements responsibly, as they may contain fuel residues. The cost of regular filter element replacement is small compared to the potential expense of fuel system or engine repairs resulting from poor filtration.
