This is the system ordered that will go in my Powerstroke diesel. I have been getting a lot of questions on how it works and thought i would summerize some info from the manufacturers site here:

• This system has undergone 3 years of development and very rigorous testing to become the most reliable, intuitive and clean installation available for the Ford Powerstroke in the world today.
• This is the only system on the market capable of being fully 100% automatic, or manual with the simple flip of a quality rocker switch.
• Not one drop of vegetable oil ever touches anything in the OEM diesel system except the injectors.
• The truck will start on the stock fuel system until the engine reaches operating temperature and V3 Manifold is over 140. Then the WVO pump comes on and starts building pressure. Once the fuel pressure exceeds 55psi(OEM spec) a pressure switch shuts off the diesel pump and the truck continues to run on WVO, and an indicator light on the system control switch on the dash lights up. Should anything at all happen to cause the fuel pressure to drop below the minimum threshold for the engine, the diesel pump kicks back on to ensure that the engine never loses pressure.
• The system is fully automated. You simply get in drive, and shut the key off. The only way the trucks differs from stock is that if you have been running WVO the truck will continue to run for up to 60 seconds after you turn the key off, kind of like a turbo timer. The purge and shutdown are all timed from us to ensure that all the WVO is purged from the fuel rails, and diesel is run back through the injectors.
• The V3 Manifold is the envy of the industry. This Billet aluminum manifold was designed specifically for this truck. Combined into one modular unit is the WVO pump, prefilter(to protect the pump), adjustable pressure regulator, air separation, Main Filter(2 micron Donaldson), pressure switch, temperature switch, Purge solenoid, and pressure test port. With the air separation there is no need to purge new filters, or worry about trapped air, it is purged automatically. Change your filter and go! And to top it off, this whole manifold has internal coolant passages and is heated with engine coolant, so besides everything else, it is a heat exchanger too.
