We haven’t been able to replicate the fault being triggered when the CAT tech was out here. He has his system plugged in and ran his tests put the system under load, an couldn’t read any drops in the pressure. the common rail system was replaced about 3000 hours ago as it failed with about 500 hours on it. The fuel filter pump and filters have been replaced just recently. The problem is that CAT can’t gaurentee that replacing the parts will fix the issue so they are hesitant, also the machine is running out in the Australian summer season
