Subject: Case Maxxum 140 Derating


South texas
I have a Case Maxxum 140, Tier 4, that has had on ongoing fuel issue for awhile now. Tractor has just over 2000 hours. It will throw error code 3141, and then derate to 1500 rpms. I can turn the tractor off, and restart it and it will go again for maybe 30 seconds, or maybe 2 hours. This only happens under a load, but has gotten more frequent recently. To this point we have changed the valve and switch on the fuel rail, the harnesses that connect to the injectors, and now the regulator solenoid on the fuel pump. Have done some testing and tractor will act up sucking fuel from a 5 gallon fuel can as well as the tank. This should eliminate an issue in the tank. I am extremely frustrated an out of ideas. If anyone has had a similar problem, or has an idea of something else to try I would appreciate it.
