Product Details
This Inline Fuel Filter is a single replacement filter for selected Mercury, Mariner, Tohatsu, and Nissan outboard fuel systems. It helps screen contaminants from the fuel supply before they reach the engine. The translucent housing makes it possible to check fuel flow and visible debris during routine maintenance.
For Mercury and Mariner applications, it replaces part number 35-16248. The corresponding Tohatsu/Nissan fuel-filter reference is 369-02230-0, also written as 369022300M in some parts systems. Always compare the part number, hose connection, and engine application before installation.
- Single inline fuel filter for gasoline outboard fuel systems.
- Installs in the fuel hose under the engine cowl or at the listed fuel-system location.
- Translucent housing allows a quick visual check of fuel and contamination.
- Suitable for the specific applications and model families listed below; model, year, stroke, and serial conditions must be confirmed.

- Install the replacement filter with the flow arrow pointing toward the engine.
- Secure the fuel lines with suitable clamps and check that the connections are fully seated.

Troubleshooting & FAQ
How do I confirm that this filter fits my engine?
Match your original filter's reference number and compare the exact engine model, year, stroke type, and hose connection with the compatibility information above. The listed references are Mercury/Mariner 35-16248 and Tohatsu/Nissan 369-02230-0 or 369022300M.
Does this fit every Mercury, Tohatsu, Nissan, or Mariner outboard from 4 to 30 HP?
No blanket 4–30 HP fitment should be assumed. The confirmed applications in the available catalog evidence are narrower, particularly for Mercury/Mariner and Tohatsu models. Check the exact application and original part number before ordering.
What are common signs of a restricted fuel filter?
Possible symptoms include hard starting, stalling, hesitation, reduced acceleration, or loss of power. Inspect the filter and the rest of the fuel system before replacing parts, since similar symptoms can have other causes.
Can I install the filter in either direction?
No. Install it in the direction of fuel flow, with the arrow pointing toward the engine. A reversed filter may restrict fuel delivery.
Is this an OEM filter?
This listing is for an aftermarket replacement filter. Mercury, Mariner, Tohatsu, and Nissan names and part numbers are used only to identify reference applications and compatibility.
What should I do if the connection does not match?
Do not force the filter or stretch the hose over an unsuitable connection. Stop installation and verify the part number, hose size, flow direction, and engine application.
Safety & Important Information
- Fuel is flammable. Work in a well-ventilated area and keep the filter away from flames, sparks, and hot surfaces.
- Verify the part number and physical connections before installation.
- Inspect the fuel hose and clamps whenever the filter is replaced.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended if you are not familiar with marine fuel systems.
