Jim:
In case anyone questions the source, the injection pump tip that I mentioned came from a large rebuilder who has seen the interval between rebuilds dropping to as low as six months on pumps with standard parts. Older pumps were designed to be lubed by high sulfur Diesel fuel. Since I was buying a rebuilt injection pump for my veggie oil non-turbo 6.2L Suburban, he strongly recommended the stainless version, which cost 50% more. Lubricity of veggie oil is far higher than any Diesel fuel, but in cold climates we start and stop the engine on straight Diesel. In Mississippi, it wouldn’t be an issue, especially in summer months.- David T.
