This is a normal diesel engine in this Jetta. What we've done is in the rear of the vehicle we've put a separate fuel tank that holds the french fry oil. That is transported to the front through these heated lines that use the actual engine heat to heat it. It comes through the filter which is also heated into the valve.  -   David Champion     Quotes
