Inspections and Adjustments
Set the lever of pressure gauge ass'y to position a.
3.
4. Measure air pressure while idling the engine or cranking
for 15 seconds.
Air Pressure : Specified Value
0.52 - 0.58 MPa (75.25 - 83.95 psi) [5.2 - 5.8 kgf/cm
The air pressure reduces gradually after
stopping the engine or cranking.
Set the lever of pressure gauge ass'y to position b to
5.
relief pressure.
6. Remove pressure gauge ass'y and attach cap.

5) Inspection of Fuel Pressure

1. Remove cap.
2. Attach pressure gauge ass'y to fuel pressure inspection
valve 1.
When attaching pressure gauge ass'y,
cover the joint of inspection valve and
gauge with rag to prevent spread of fuel
that leaks.

it is set securely.
Pressure Gauge Ass'y:
P/N. 3T5-72880-0
Set the lever of pressure gauge ass'y to position a.
3.
4. Measure fuel pressure while idling the engine or cranking
for 15 seconds.
Fuel Pressure : Specified Value
0.58 MPa - 0.66 MPa (83.95 - 95.55 psi) [5.8 - 6.6 kgf/cm
Do not move the lever of the gauge during
the measurement. Moving the lever causes
highly pressurized fuel to blast out, which
is very dangerous.
The fuel pressure reduces gradually after
stopping the engine or cranking.
