Attention: TDR Forum Junkies 
I am a bit skeptical about heating the oil with the expectation that you will be able to run WVO thru a cold engine block. Part of the problem is, based on the study linked below, the WVO burns properly only when it is heated to a temperature of between 212 and 266 deg F and at pressures above 20 bars. If you read the study below, what it seems to say, is that the VO doesn't burn properly at the lower temps and pressures that petroleum based No. 2, and failure to adjust for that will lead to undesirable carbon polymerization in the combustion chamber of the engine. If you run the VO in a cold engine, you are not taking advantage of the heating effect of the hot engine on the fuel system, though I'm not sure how hot the VO will get between the tank and the injector nozzle on a hot engine.
"With vegetable oil fuels pockets of burning could be seen, some of which persisted for long times suggesting that these were larger droplets which burned as a diffusion flame for times longer than the available than those available in an engine. Thus they were potential carbonising nuclei for the walls of a burner or engine. " *
*"As a summary, it may be recommended, for any attempt of using VO in an engine, to use the rape seed oil at relatively high temperature, of order 100-130 °C. "
