Purge Bulb
The elastomer material of the bulb undergoes chemical degradation and oxidative stress over time, leading to embrittlement and stress-cracking. Once the structural integrity of the bulb is compromised, fuel escapes the pressurized chamber during the manual priming stroke. Replacing the bulb restores the hermetic seal required for the vacuum-pulse fuel delivery system.

Fuel System RePower Kit
In many Echo SRM-225 units, the leak at the primer bulb coincides with the failure of the fuel tank grommet and return lines. This kit includes the bulb, lines, and grommet, addressing the high probability that the same chemical degradation affecting the bulb has also compromised the adjacent fuel delivery seals and tubing.

Carburetor Purge Base Assembly
If the leak persists after bulb replacement, the plastic purge base or the check-valve within the carburetor's upper body may be warped or cracked. This prevents the bulb from seating flush against the carburetor body, allowing fuel to bypass the gasket during the pumping cycle.
