I have a hand pump that goes on the m/c, but I actually prefer to use a mason jar and a pice of small hose. Just fill the mason jar up about a quarter way with clean brake fluid. Put the hose on the bleeder and make sure the other end is submurged in the fluid and pump. You don't need a second person, when you release the pedal, it won't suck air in the system, just fluid. No spraying fluid all over the place. Just make sure you don't run the master cylinder dry.
