The truck is a 95 350 with 145K.
I purchased a Greasel kit and installed it last Saturday.
I added an electric tank switching valve on the return line so when the engine is running WVO flows back to the tank instead of looping the return back to the fuel pump. If the fuel filter on my WVO plugged them I would pull fuel thru the return line to the pump bypassing the heated WVO filter.

The plan is to run a mix of diesel and WVO in my heated front tank and bio-diesel in the rear.
