Description
Overview:
This genuine Stihl impulse hose (MPN 1123 141 8600) is a small but critical engine component for Stihl chainsaws. Made from durable, fuel- and oil-resistant black rubber, it carries pressure pulses from the crankcase to the carburettor to operate the fuel pump diaphragm. A sound impulse hose helps maintain reliable fuel delivery, smooth idling and strong acceleration under load. Designed for a precise fit on Stihl models such as the 021 and 023, it replaces aged, split or leaking hoses that can cause hard starting, lean running or stalling. As a genuine part, it matches the original specification for length, bore and flexibility, making it a straightforward, dependable choice for routine maintenance and repairs on compatible Stihl saws.
Key Features:
- Genuine Stihl part for correct fit and performance on listed models
- Tough rubber construction resists petrol, oil, heat and vibration in everyday use
- Maintains consistent carburettor fuel delivery for smoother idle and throttle response
- Helps cure air leaks that lead to hard starting, surging or poor acceleration
- Precisely moulded to the original specification for easy, push-fit installation
- Stable flexibility for secure sealing at both crankcase and carburettor connections
- Suitable for preventive maintenance during carburettor service or rebuilds
- Supports reliable cutting performance by restoring correct pulse transfer
- Replaces worn or perished hoses without modification to the saw
Typical Applications:
Used during chain saw servicing to replace a cracked or leaking impulse hose, particularly when addressing starting issues, erratic idle, loss of power or fuel delivery faults. Common in workshop rebuilds, field repairs and routine maintenance for arborists, landscapers, trades and home users who need dependable operation from their Stihl saws.
