Recently we had a call out to Toowoomba as a mack trident had an injector fault, running rough and low on power.
We attended and found that no3 injector was open circuit.
We replaced the injector and cup and also found the culprit for low power. The fuel return line was completely blocked.
With a new injector, injector cup installed and programed. New fuel line, this truck was back on the road.
