hey grimlin, there was a thread going a few weeks ago about this titled "Boidiesel/Vegetable Oil". i am in the process of installing a kit to run my truck on used fryer oil. i tell about it in the post. check out the website for neoteric. it takes some doing but it's not that difficult. takes a bit of dollars too but you get free fuel. i'm going on vacation coming up soon so i'm busy getting things wrapped up here before i go. so sorry if i don't answer your posts. you could also check out a veggie oil discussion group -- the url is given in the "Biodiesel" thread. good luck!
