I recently puchased a 1997 F250 Powerstroke with the intentions of converting it to run on waste veggie oil. It has come to my attention after purchasing the truck that the 7.3 in the 97's is not the best option for conversion unless you add an addition fuel pump for the veggie oil. (which the recommended one is $400-500). But apparently the 7.3 in the 1996 F250 is much easier/better for WVO conversion.

So here is my question/bid for advice:

Do I sell the 97 and look for an older F250 with the IDI engine, or go for it with the 1997 and purchase all the extra parts needed to complete the conversion??????????

Any help is greatly appreciated.

What is the difference between the 1996 and 1997? My light research on the topic would imply that there is not a significant change between the years 1994-1998. Correct me if I am wrong but I believe this generation comes with a mechanical fuel pump. High quality conversions from DFA replace this pump with an electric one and then add an additional pump for Veggie. Personally, I believe that it is a good idea to add an independent fuel system for veggie just for the redundancy. Either case you could probably "Get away" with using the mechanical fuel pump for both fuels if you wanted to go that way. Especially since it sounds like you have a dedicated vehicle for WVO use.
