Rust Inside Pump Socket = Leaking Pump
Sometimes, the rusting on the motor shaft can get so bad that you can't pull the pump off. In these cases, you may need to resort to a destructive removal. The pump is just plastic and can be removed with hammer, chisel, drilling, whatever works. Doesn't matter how ugly it gets because the pump is being replaced anyway. The motor is pretty sturdy-- just avoid getting plastic shavings down in the winding-- could melt and smell funny.
