Husqvarna 350BT 50.2 cc Gas Backpack Leaf Blower PRIMER BULB Error Fix: Primer Bulb Cracked or Not Priming

The primer bulb is cracked, hard, or does not draw fuel when pressed — the primer bulb draws fuel from the tank through the carburetor to enable easier starting; a cracked or hard bulb will not create suction; press the bulb 5-10 times until fuel is visible in the return line; if no fuel moves, the bulb is cracked and needs replacement; also check the fuel lines connected to the bulb for cracks or loose connections; primer bulbs harden and crack from UV exposure and fuel chemical exposure over time
