Faulty purge bulb on a leaf blower

The purge bulb works by drawing fuel through the fuel filter, fuel line and carburettor. Then it pushes the fuel out the return line into the tank.

• If the purge bulb will not compress, check the lines as they are likely to be connected backwards.
• If the bulb will not come back out, check the fuel filter, fuel line and carburettor for blockages.
• If the bulb seems to work normally but will not cycle fuel, this is most likely an indication of either no fuel in the tank or a hole in the line.
