If everything is working correctly, you shouldn't need to add another check valve. Just trace what you have and see if it has been screwed with in the past by a previous owner, or if there's a failure in one of the existing check valves.

Hmm. I believe you're correct, looking at the PET diagrams. Sorry for introducing confusion. Maybe you can help me understand something.
Yesterday, I was trying to diagnose a few problems with my washer system. I ended finding a leak in one line by the battery. It's the one on the high pressure side of the main windshield pump that T's off and goes back to the large tank. Not having the right parts, I spliced in a bit of fuel line using a barbed connector, intending to get the right line this week. I also replaced the T using one with the same ID.
Once I did this, I got some fluid out of the windshield nozzles, but not much. Once I crimped off the T'd line that goes back to the main tank, I got plenty of pressure. However, at that point I noticed the intensive tank was getting filled.
So, what is the point of that line that T's off after the pump and goes back to the tank? Some sort of pressure balancing?
