A properly functioning lift pump supports consistent fuel supply during engine starting and operation, making it an important component of the excavator's diesel fuel system.
When Should the Fuel Transfer Pump Be Checked?
Inspection may be necessary when the machine experiences symptoms such as difficulty starting, insufficient fuel delivery, unstable engine operation, loss of performance or visible leakage around the pump.
These symptoms can also have other causes, so the fuel system should be properly diagnosed before replacing components.
