let's treat it like any other diesel engine. Locate The primer pump, either on the filter or on the cylinder block. open the bleed valve at the injector pump inlet. Pump the primer until all the air is out to the injector pump housing. Then close the bleeder. If tractor will not start then, you will need to loosen the high pressure injection lines at the nozzles on the cylinder head, then crank engine until you have fuel squirting , then tighten the lines and start the tractor, when it starts run it at half throttle to clear any left over air from system.
