Anyone done a DIY wvo conversion on a 6.0?

Hey guys, I'm strongly thinking of switching my 04 6.0L to a 2 tank system for wvo, but I have a few questions and am looking for some help.

- the first part has to deal with the diesel system. if a two tank system is run with the wvo going directly to the heads, how do you not throw a code for low fuel pressure since the fuel pressure regulator is right off of the fuel filter and bowl under the hood? also, how do you not throw a code when you switch from the D2 fuel pump to the wvo pump (i plan to have my setup on two two way switches so that I can turn each fuel pump on or off seperatly which will allow me to run the wvo pump for a few seconds while the D2 pump is running so that there is not a drop in pressure at the rail)

-since the stock fuel checkvalves allow fuel to flow backwards to account for pressure spikes due to the split injectors the check valves need to be replaced. how are the pressure spikes managed since the new check valves are actual check valves, and how is the fuel pressure released from the heads when the truck is shut down since the original D2 return line runs back to the tank from the fuel bowl.

alot of wvo systems have fuel pressure release valves - how and where would I install this on the 6.0

- i have heard that the alternative fuels will degrade the injector o-rings since ford switched the formula for the rings in the 6.0s. is there any truth to this and does it need to be done for wvo?

- also is the bosch high pressure fuel pump suitable for wvo and the temperature?
