i wonder how many of you know or understand the benefits vegetable oil as a fuel? i have a diesel bus and im thinking about installing a vegetable oil system into my fuel system.my friends are already doing this but they are having trouble keeping fuel up to tempature when it hits the injecters. so my question is do any of you own a veggie system or know of a sucessful system operating around. i have met and seen running systems but i wasnt able to inquire about the installion of the system. cost is a factor, one person told me that it was going to cost 3000 for a system to be built. which is not a lot unless your like me with very little money. i would want to build my own. greasel makes a kit but once again it would cost me a fortune to get the 100 gallon tank that i would want. biodiesel is an option but i have 3 children ,and to have to carry the chemicals that is required to process it is a situation for us right now, that would require a trailor where as i need a car.
