I will again reccomend HOH. If you look at the conversion companies products (Greasel etc) I think you will find none of them use HIH anymore either. Especially since you are dealing with a 300D. These buggers love vege and there are known to be ones on the road overseas that run pure oil with no conversion at all.

Use the hose on hose just to help the fuel flow from the tank. Honestly you may not even need that If corpus cristy is a warm TX climate and you dont venture far from it. Do a final heating of the oil to the temp needed for better combustion up in the engine compartment via a home made or commercial coolant/fuel heat exchanger or a 12v one orrr?.

For more information a discussion on this conversion is going on over at Maui Green SVO Forum
