This is a fuel pump diaphragm repair kit, not a complete replacement fuel pump. Kit contents may vary between manufacturers.
OEM part numbers are used for identification purposes only.
Important – Check Compatibility
Please confirm your Suzuki engine model, serial number and original fuel pump part number before ordering.
Different fuel pump designs were used across these horsepower ranges, and not all diaphragm repair kits are interchangeable.
If the parts look the same as yours, this does not always mean they are correct for your outboard.
If unsure, contact SSI Marine with your engine details before purchasing. Our technical team will be happy to assist.
