Energy Cell? The 262 Buda has injectors and air heaters. My parts book does not show an energy cell. I've never had a diesel with an energy cell. Is that something like a glow plug?
If you are looking for injectors, I believe you can get them from AGCO Allis but they might be quite expensive. You can take them to a diesel shop and have them rebuilt a lot cheaper - rebuilt means thoroughly cleaned and the seat refinished.
