If a diesel powered truck runs out of fuel, it will not restart after you have obtained some diesel and put it in the tank. A diesel will not pull the fuel from the tank to the engine if the fuel line is full of air. You must first prime the engine with fuel before attempting a successful restart.

Step 1

Look in the owner’s manual for the location of the fuel primer pump and bleed screw. The pump and screw will be located somewhere near the fuel filter on the engine. The primer pump will be a large push button, rubber bulb or small lever.

Step 2

Loosen the bleed screw a couple of turns. The loose bleed screw allows the air to leave the fuel line as the fuel is pulled from the fuel tank to the fuel filter.
