I am planning the conversion of my 88 7.3 IDI NA to WVO soon. The stock mechanical lift pump feeds the fuel filter/separator before going to the IP. The fuel filter is under pressure from the lift pump. Where should I tie in with the 3 way valve? I would like not to run veg through the diesel fuel filter. I'd like to use the mech lift pump also for veg if possible and not add an elec pump.
