INSPECTION

CAUTION:
^ Before removing the fuel pressure gauge, release the fuel pressure.
^ Be careful not to spill fuel.
^ Catch the fuel from hoses using a container or cloth.


NOTE: Check or replace the fuel pump and fuel delivery line if the fuel pressure is out of the standard.

1. Release the fuel pressure.
2. Open the fuel filler lid, and remove the fuel filler cap.
3. Disconnect the fuel delivery hose from the fuel damper, and connect the fuel pressure gauge.





4. Start the engine.
5. Measure the fuel pressure after warming up the engine.

NOTE: The fuel pressure gauge registers 10 to 20 kPa (0.1 to 0.2 kg/cm2, 1 to 3 psi) higher than standard values during high-altitude operations.

Fuel pressure:
Standard: 338 - 348 kPa (3.4 - 3.5 kg/cm2, 49 - 50 psi)
