The purge bulb has a bayonet fitting on the back, squeeze them together and the bulb assembly will pop out, if you cannot get to the back of the bulb assembly, gently tease it out with a screw driver from the outsde, be carful not to damage the housing, re connect the two hoses to a new purge assembly, making sure you do not mix them up, the longer tube on the purge pushes the fuel back to the tank, the short tube is a suction tube and draws fuel fronm the carb.
