HELP!!!

My washer is leaking while spinning. I have taken the front panel off and identified where the leak is coming from. As best I can describe, on the back left corner connected to the outer tub there is a hollow white plastic tube that runs from the top of the tub where it is connected almost to the drip pan...while spinning the water is coming out of the bottom of this tube. It seems there was never a cap put on the tub, or it fell off or, I am completly wrong and water should come out of this....any help would be great.

Thank you - Jim
