Key Features
- OEM Fuel Metering Accuracy — Manufactured to Husqvarna's original specification, this injector delivers the precise fuel atomization and dosing the FS309 engine requires for clean combustion and steady power output.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and connector interface of the FS309, allowing straightforward installation without modification.
- Confirmed FS309 Compatibility — Specifically validated for the FS309 floor saw, giving you confidence that the part you're installing is the correct one for your machine.
- Restored Engine Performance — A correctly functioning injector maintains the fuel-air balance the engine needs for smooth starts, stable throttle response, and consistent cutting power through demanding concrete slab work.
- Fuel System Integrity — Using a genuine OEM injector helps maintain the integrity of the fuel system, reducing the risk of rich or lean conditions that can cause overheating, misfires, or long-term engine wear.
The injector is responsible for delivering a precisely metered and atomized spray of fuel into the engine's combustion chamber at the correct moment in the firing cycle. When the injector is functioning properly, the engine runs efficiently with strong, consistent power — essential when the FS309 is pushing through dense concrete or working extended cuts. A worn or clogged injector disrupts the fuel-air mixture, leading to hard starts, rough running, loss of cutting power, and increased fuel consumption. Replacing a failing injector with a genuine OEM part restores the combustion characteristics the engine was designed to operate on.
