Hope this answers your question. If I remember right, open the valve 2 or 3 turns, have someone turn the key on, and catch the fuel/water coming out the little tube as the system is pressured. I got messy trying to just open the valve till I got fluid, and I was not the only one.
The valve is in on the left side; look through the front wheel well you will see a black filter with a clear plastic tube. The valve is light gray with a clear plastic tube attached. The filter also has a two conductor electrical connection attached.
