Product Details
This aftermarket Vapor Separator Tank (VST) fuel filter is a replacement filter for selected Yamaha and Mercury Mariner 4-stroke outboard fuel systems. It installs inside the VST or fuel-injection pump assembly to help screen contaminants before fuel reaches the high-pressure fuel pump.

Catalog references also associate the corresponding filter with selected Mercury 115 EFI and 225 EFI 4-stroke applications, subject to the model, serial-number range and service-manual conditions shown below.
- VST fuel filter for gasoline outboard fuel systems.
- Internal installation inside the VST or fuel-injection pump assembly.
- Single replacement filter; no gasket or other VST components are included.

Troubleshooting & FAQ
Where is this filter installed?
This is an internal VST fuel filter used in the vapor separator or fuel-injection pump assembly. It is not the external low-pressure or water-separating fuel filter.
Does this product include a gasket?
No. The company record identifies this product as a single filter. A gasket or float-chamber seal is not included.
How do I know whether my engine uses this filter?
Match the complete engine model, year and serial-number range with the fitment information and compare the original filter's part number. Horsepower alone is not sufficient to confirm fitment.
What symptoms can indicate a restricted VST filter?
Possible symptoms include hesitation, sputtering, loss of power under load or failure to reach normal operating RPM. These symptoms can have multiple causes, so diagnose the complete fuel system before replacing parts.
Can I clean and reuse the old filter?
Replacement is recommended when the filter is contaminated, damaged or restricted. Cleaning may not remove fine particles and can damage the filter media.
Is this an OEM component?
No. This is an aftermarket replacement for the listed OEM and aftermarket reference numbers. Mercury, Yamaha and Sierra are referenced only for identification and compatibility purposes.
Safety & Important Information
- Confirm the exact engine model, year, serial-number range and original part number before ordering.
- Do not assume compatibility with every 115 HP, 200 HP or 225 HP outboard.
- Use the engine service manual for fuel-system disassembly, pressure relief and reassembly procedures.
- Inspect for fuel leaks before operating the engine.
- Professional installation is recommended when working on pressurized gasoline fuel systems.
