I am pretty sure he is using the proprietary Greasecar 3-way valves. These also have known to leak. In my Greasecar kit the valves seemed that all the nuts and screws were loose. I made sure everything was snug before I installed it. I also took made sure there was no air leak by taking a Mity vac to it and testing the pressure.
surfblau, As far as your car starving with only a half of tank of fuel, I would check the tank strainer at the bottom of your fuel tank. Many times there is a possibility that the purge process during shut down is not complete and some vegetable oil can get into the diesel tank. This diesel and vegetable mixture will act like a solvent and clean your tank walls. All the sediment will then get stuck at the tank screen. When you have a full tank, there will be enough pressure to push through the screen. But once you have a half of tank the pressure drops and it is not strong enough to push through.
So I would check those two things first. Especially if you have a combination of the two, then it make the problem worst.
