Description
Overview:
The Impulse Hose for Husqvarna K 770 petrol disc cutters is a Genuine Husqvarna OEM part designed to carry crankcase pressure pulses to the carburettor, helping the fuel pump operate correctly under load. Made from a tough, fuel- and oil-resistant elastomer with a flexible black finish, it is built to handle engine heat and vibration without cracking. This hose fits directly to the existing ports on the machine for a clean, secure seal. It is suitable for Husqvarna K 770 and K 770 Dry Cut variants, along with other selected K 770 and K 760 series models. Replacing a perished or leaking impulse line restores stable idling, consistent acceleration, and reliable cutting performance. Manufacturer Part Number (MPN): 586 22 77-01.
