Description
Overview:
This genuine Stihl impulse hose (MPN 4180 141 8601) is a small but critical rubber line used on many Stihl 2‐stroke machines, including the HL100 and HL100K. Made from fuel‐resistant rubber, it transfers the engine's impulse (vacuum/pressure pulses) between components, typically from the crankcase to the carburettor or pump, so fuel delivery stays consistent. A sound impulse hose helps engines start reliably, idle steadily, and pull cleanly under load. As a direct replacement for the original part, it restores correct routing and sealing where the original hose may have hardened, split, or perished with age. Genuine Stihl manufacture ensures the correct fit and material specification for long service life in brushcutters, hedge trimmers, Kombi engines, pole pruners, and other compatible tools.
Key Features:
- Genuine Stihl part for assured compatibility and correct fitment
- Direct replacement for OEM 4180 141 8601 (also 4180-141-8601, 41801418601)
- Durable, fuel‐ and oil‐resistant rubber for small engine environments
- Maintains a tight seal to preserve accurate impulse signals
- Helps restore reliable starting, stable idle, and smooth acceleration
- Formed to suit OE routing for a neat, interference‐free installation
- Suitable for a wide range of Stihl handheld machines in the FS/HL/HT/KM series
- Simple push‐on fitting using existing connectors and clips
Typical Applications:
Used during routine servicing or repairs when engines are hard to start, won't idle, or hesitate under throttle. Ideal when the original hose shows cracking, stiffness, or fuel leakage. Commonly replaced alongside carburettor service kits, fuel lines, and filters on hedge trimmers, brushcutters, Kombi power units, pole pruners, and augers to restore dependable operation.
