3. Fill the fuel tank with diesel and press the exhaust hand pump to allow the diesel to enter the engine through the filter.
4. Connect the inlet and outlet pipelines of the water pump and the gate valve, close the gate valve of the outlet pipeline, the outlet pressure gauge, and the vacuum pressure gauge.
