Purge Bulb
The purge bulb elastomer has reached its fatigue limit due to chemical degradation from ethanol-blended fuels and UV exposure. This degradation causes the polymer to become brittle, leading to stress cracks during compression that prevent the vacuum necessary to draw fuel from the tank. Replacing the bulb restores the pneumatic seal required for the priming circuit.

Fuel Line Kit
Fuel lines are manufactured from similar elastomeric materials as the primer bulb and are subjected to the same environmental stressors. If the bulb has cracked due to age or chemical rot, the fuel lines often exhibit internal collapse or external 'sweating' leaks. Replacing the lines ensures that air is not introduced into the fuel system through secondary leak points.

Carburetor Gasket and Diaphragm Kit
The internal rubber diaphragms in the carburetor act as the pulse pump and metering valve; these components degrade at the same rate as the external primer bulb. If the primer bulb is cracked, the internal pump diaphragm is likely stiff or perforated, which will prevent the engine from maintaining a consistent fuel-to-air ratio after the priming stage.
