The Husqvarna 586227701 Impulse Hose is a genuine OEM component designed for the K760, K770, and K760II power cutters. As a direct factory replacement, this hose restores the correct pressure signal between the crankcase and carburetor fuel pump, ensuring the engine runs as intended. DHS Equipment supplies this part to help keep your equipment running at peak performance.
Key Features
- OEM-Grade Fuel and Pressure Compatibility — Manufactured to Husqvarna's exact material and dimensional specifications, this hose maintains the correct flexibility and fuel-resistance needed to handle crankcase impulse pressure without cracking or collapsing over time.
- Drop-In Replacement Fit — Engineered to match the original routing and connection points on K760, K770, and K760II power cutters, this hose installs directly without modification.
- Broad K-Series Power Cutter Coverage — A single part number covers the K760, K770, and K760II, making this the correct choice across several of Husqvarna's most widely used construction power cutters.
- Fuel Pump Signal Integrity — A functioning impulse hose delivers consistent pressure pulses to the carburetor diaphragm fuel pump. A cracked or blocked hose causes hard starting, erratic idling, and loss of power under load.
- Fuel System Safety — As a component in the fuel delivery circuit, an OEM hose built to the correct pressure rating helps prevent fuel leaks that could create a fire hazard on the worksite.
The impulse hose connects the engine crankcase to the carburetor's integral fuel pump, transmitting pressure and vacuum pulses generated by piston movement to draw fuel from the tank into the carburetor. Without a functioning hose, the fuel pump cannot operate correctly, resulting in fuel starvation, rough running, or a complete inability to start. Because the hose is exposed to fuel vapors and mechanical vibration, it can harden, crack, or collapse with use — and replacing it with a genuine OEM part ensures the correct fit, flexibility, and resistance to restore normal engine operation.
