   NOTE:

   • Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because this models do not have fuel return system.
   • Use Fuel Pressure Gauge Kit (J-44321) to check fuel pressure.
3. Connect pressure gauge (B) to fuel pressure check adapter.
4. Turn ignition switch ON and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge.

   At idling: Approximately 350 kPa (3.5 bar, 3.57 kg/cm ²  , 51 psi)
