The Husqvarna 579042601 Fuel Pump is a genuine OEM component designed for the FS4600 floor saw. As a direct Husqvarna OEM part, it is built to the exact specifications of the original, ensuring correct fuel delivery and consistent engine performance. This fuel pump is the right solution when the original has failed or degraded, restoring the FS4600 to full operating condition. DHS Equipment supplies this part to help keep your equipment running on the job.
Key Features
- OEM Fuel System Precision — Manufactured to Husqvarna's exact flow rate and pressure specifications, ensuring the engine receives consistent, correctly metered fuel delivery at all operating loads.
- Exact-Fit Replacement — Engineered to match the original mounting configuration and port sizing of the FS4600, allowing this pump to install directly in place of the worn unit.
- FS4600 Floor Saw Compatibility — Purpose-built for the Husqvarna FS4600 floor saw, so you can cross-reference part number 579042601 against your parts diagram with confidence.
- Restored Engine Responsiveness — A correctly functioning fuel pump sustains steady fuel pressure through demanding cutting cycles, preventing the rough running, stalling, or hard starts that accompany pump failure.
- Fuel System Integrity — Genuine OEM construction means correct seal materials and diaphragm grades, reducing the risk of fuel leaks that can create a fire hazard on a working saw.
The fuel pump is responsible for drawing fuel from the tank and delivering it to the carburetor at the pressure and volume the engine requires. On a floor saw like the FS4600, which operates under sustained load during concrete cutting, a failing pump causes fuel starvation — leading to rough running, loss of power, or the engine cutting out entirely mid-cut. Replacing a worn pump with a genuine OEM unit restores correct fuel flow, bringing the engine back to its full power output and making cold starts reliable again.
