Fuel Leakage Inspection

WARNING:
  • Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Always carry out the following procedure with the engine stopped.
CAUTION:
  • Connecting the wrong DLC terminal may possibly cause a malfunction. Carefully connect the specified terminal only.
  1. Short the DLC terminal F/P to body GND using a jumper wire.
  2. Turn the ignition switch to ON position to operate the fuel pump.
  3. Pressurize the system this way for at least 5 minutes  to be sure of no leakage.
    • If there is fuel leakage, inspect the fuel hoses, hose clamps, and fuel pipe sealing surface and replace as necessary.
  4. After repair, assemble the system and repeat Steps  3 to  3.
