My father has three d-6 cat tractors. None are running at this time. He is building one good machine from three, one engine is running with starting fluid,or gas soaked rag. I am to the conclusion it has a fuel problem... does anyone know what the supply pump pressure should be? Factory guage is broken. Also, any idea how to remove the suppy pump? It moved it 1/4 inch and now it seems to be catching on something. I have checked injector lines and not getting a high pressure spray. We have pulled sock filters and cleaned fuel housing. Any and all tricks would be appreaciated.
May your tractors always be yellow,
