Description
Overview:
This Genuine Stihl impulse hose (MPN 1115 141 8600) is a flexible rubber line used in petrol chainsaws to transfer pressure pulses from the crankcase to the carburettor fuel pump. By delivering a steady impulse signal, it helps maintain consistent fuel flow for smooth idling, clean acceleration, and reliable cutting performance. Made from durable, fuel- and oil-resistant rubber, it is sized and moulded for the correct routing and seal on compatible saws such as the Stihl 048 and 045. A sound impulse hose is vital for preventing air leaks and lean running, especially on older or hard‐worked machines. This OEM component is suitable for professional users and DIY owners who want dependable operation and straightforward maintenance.
