7.3L Engine


Allow the vehicle to sit for at least 10 minutes. The 7.3L diesel engine fuel system will internally relieve system fuel pressure after approximately 10 minutes.

Before removing the fuel tank filler cap, turn the fuel tank filler cap 1 / 4 to 3 / 4 turn counterclockwise and wait for the tank pressure to be relieved. Personal injury may result if the fuel tank filler cap is removed without the pressure fully relieved.

  1. Before servicing the vehicle, refer to the Precautions Section.
  3. Remove the fuel tank filler cap to relieve any pressure in the fuel tank.
  5. When servicing the fuel lines, loosen the fuel fitting to allow any residual fuel line pressure to be relieved.
