Hello Keith,
Thanks for all the helpful information. What a sin that so much waste
of resource is going on. I will post what I find when I titrate the rice
oil.
It's also very helpful to get the info on the Elsbett kit. I did speak
to a mechanic in Sonoma County, CA, who is using Neoteric components, he has
been the only mechanic so far who spoke about the injector and glow plug
issues with SVO conversions.
So much to learn. It's wonderful to have such a terrific site and
community to help in the process! I will pass the information on.
Take care, Frieda
