Depending on how often the little machine starts and its age, the inside of the bulb will eventually get gooey, causing it to stick. If a brittle bulb cracks around the seal, air will leak out the side rather than force fuel from the tank into the bulb, also causing a collapse.
Bypassing a primer bulb is simple. Just disconnect the carb line and plug it with a ball bearing to seal it entirely. Then, connect it back to the carb. Ensure that any possible air leakage spots are dealt with properly.

How It Works. Pressing the primer bulb creates a vacuum that sucks gas from the fuel tank through the fuel lines and into the carburetor. Pressing the primer only a couple times should supply enough fuel to mix with air in the carburetor, and be ready for combustion.
Outboard engines lose fuel prime because of an air leak in the fuel system. Somewhere between the engine and the fuel tank.
Why is gas leaking from the primer bulb?
It could be a worn rubber gasket inside the carburetor or a bad float needle. The fuel line might have a hole or could be clogged with debris. The problem might lie with the fuel filter or fuel pump.
