We went back to the farm drained all the fuel and changed filters put in fresh fuel, atf, and 3 fuel additives in our 4320 and 4020. The 4320 ran like it did before and would only turn about 1500 rpms. We ran it for a while and took it out too the field and put it under a load for a while and after a few minutes it would rev up 2000 rpms but not under a load. The 4020 after everything would not run except on ether even pulled it for a while. Not sure if some thing is stuck or plugged. We checked the screens on the return fittings and found them clean. Not sure if pump or injectors or both are damaged. Any thoughts?
