Fuel Pressure: Testing and Inspection
NOTE:
^
When reconnecting fuel line, always use new clamps and be sure to position them correctly.
^
Use a torque driver to tighten clamps.
^
Use Pressure Gauge (J-2540034) to check fuel pressure.
Fig. 1 Typical fuel pressure gauge installation
1. Release fuel pressure to zero.
2. Disconnect fuel hose between fuel filter and fuel tube (engine side).
3. Install pressure gauge between fuel filter and fuel tube.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
At idle:
Approximately 206 kPa (2.1 kg/cm2, 30 psi)
The moment accelerator pedal is fully depressed:
Approximately 255 kPa (2.6 kg/cm2, 37 psi)
6. Stop engine and disconnect fuel pressure regulator vacuum hose from intake collector.
7. Plug intake collector with a rubber cap.
8. Connect variable vacuum source (J-23738 or equivalent) to fuel pressure regulator.
