You won't be able to just pull the pump to get the belts tight enough. You'll need some leverage. What usually works well is a crowbar on the bolt right behind the pulley - you can pull against the crankcase and the crowbar will keep the bolt from turning while you tighten it with the other hand. If you can't get that to work, look into getting some belt tensioners that mount under the motor.
