3. Verify that there is no fuel leakage from the pressurized parts.

  Standard

  There shall be no leakage after 5 min.

4. In the case of fuel leakage, replace the following components and then do the recheck by the fuel leakage checking procedure.

  • If there is leakage, replace the fuel hoses and clips.
  • If there is damage on the seal on the fuel pipe side, replace the fuel pipe.
