Product Description

The HUSQVARNA 598611001 is a tank vent valve assembly designed to regulate pressure and allow controlled venting of fuel tank vapors in outdoor power equipment. This assembly prevents pressure buildup and vacuum lock within the fuel tank, ensuring consistent fuel flow to the engine.
