That is not quite how it works... Just like the 7.3, the 6.0 uses an electric fuel pump to supply ~55psi to the HEUI injectors, which use high-pressure oil to increase the fuel pressure - up to 20,000psi. The 6.0 injectors are just much less forgiving to low fuel pressure than the 7.3 - this is primarily the reason we hear of more 6.0 injector failures than 7.3 failures.
I know quite a few 6.0's with LOTS of successful miles on WVO. There is a 'right way' to do it.

Do you use biodiesel? Why do you need to change the filter more often? Even the often-repeated rumor about bio-d 'cleaning out' the fuel system and clogging up fuel filters is not always true.
I strongly recommend a FUEL PRESSURE gauge to anyone considering alt. fuels or more HP in these trucks. As long as the gauge sender is post-filter, you'll KNOW what the condition of your filter is and know when it really needs changed, instead of just guessing!
