Oh, I guarantee it will swirl. The forces that would cause it to be sucked out of the outlets (suction of the pump) would come in a straight line into the outlets, not at an angle from the intake (like is supposed in your statement). The force from the inlet would be straight down over the cone. Slowly (in this case a couple of seconds) momentum in the fluid would build until there is a tornado effect inside of the block. This is why a strong pump is required. If the pump barely has the guts to power the system, it may not be able to trigger this effect that well.
The red is F and the blue is water flow.
