[keepitgreen05]

It varies.
Depending on the fuel pumps ability, the vacuum applied, the condition of the carb seats, fuel delivery, etc.
My normal take, if the engine does not have a problem then there is no problem.
Ended up replacing a fuel pump on my daughters boat last week and the bubble stayed tighter than when I owned the motor.

Technically the primer bulb is just to get the fuel to the carb initially then the fuel pump takes over. At that point the bulb becomes a fat piece of fuel line.
