To prime a diesel after running out of fuel: Fill the tank with diesel. Locate the fuel primer pump, typically on or near the fuel filter. Pump the primer until it becomes firm, indicating the system is filled with fuel. Loosen the bleeder screws on the fuel filter to allow air to escape. Continue pumping until only fuel exits. Tighten the screws and start the engine. Repeat if necessary. Ensuring no air remains in the system is crucial for smooth operation.
