Before you start

  • Fuel bleeding may be required after replacement of any fuel system component including hoses, filters, and fittings.
  • Fuel bleeding may be required after draining of fuel filter/water separator.
  • Fuel bleeding may be required after running the engine out of fuel.
  • Fuel bleeding may be required after extended periods of storage.
  • Two wrenches must be used when loosening or tightening the high-pressure lines at the injectors to provide counter torque. Failure to do so will result in the bridging pipe between the injectors being damaged.
