Put a real fuel filter/water separator on it. You can buy the Roosa Master filter pair from a tractor salvage yard. Most John Deere Diesels from 4020 on have them. Most of the problems of the GM diesel stem from water in the fuel/plugged filter. The factory put on an itty bitty filter, not much more than the MB see-thru prefilter, that passes ALL water through to the nozzles, where it ruins them.
Side benefits of the Master filters: They are see thru; you can buy replacements lotsa places, including every JD dealer in the country. If you are stranded, you have about a 50/50 chance of the nearest farm having spares; they filter out finer particles than the MB OEM filters.
