Genuine Stihl 4223 141 8600 / 42231418600 impulse hose for compatible Stihl TS 400, TS 700 and TS 800 cut-off saws. The impulse hose carries pressure pulses from the engine crankcase to the carburettor fuel-pump circuit, helping the carburettor deliver fuel correctly while the engine is running. Suitable for replacing a split, cracked, hardened, leaking or otherwise damaged original impulse hose, particularly where an air leak may cause starting or running problems. Manufactured to Stihl specifications for the correct moulded shape, fit and airtight connection. Parts documentation identifies 4223 141 8600 specifically as the impulse hose.
