Description
Overview:
The SED Pulse (impulse line) is a Genuine Husqvarna spare part designed for small two‐stroke chainsaws. Made from fuel- and oil‐resistant elastomer, it carries crankcase pressure pulses to the carburettor's fuel pump, helping maintain steady idling, clean acceleration, and reliable starting. This direct‐fit replacement restores correct fuel delivery when the original hose has perished, cracked, or become loose. It is engineered for Husqvarna saws, including models 136 and 137, and matches the original routing and connections for a secure seal. Supplied under OEM number 530 05 34‐35 (MPN 530053435), it delivers the fit, function, and durability expected from a factory component. Suitable for trade users and DIY owners who need a dependable fix without modifying the machine.
