98.5 to 2002 24 Valve with the VP44 Injection Pump
If it is between the years of 98.5 and 2002, and has a VP44 injection pump, sadly we do not advocate the conversion of this engine, at this time. We have spent allot of time and Money analyzing the effects of veggie oil on this pump. In the end, although veggie oil was not directly linked to the failure of the VP44 injection pump (it was an electronic problem, not mechanical) there were enough gray areas that we determined not to advocate conversion of this pump. The 03 and newer 24 valves are fine, and do not have any problems.
