Fuel Pressure Check

- When reconnecting fuel line, always use new clamps.
- Make sure that clamp screw does not contact adjacent parts.
- Use a torque driver to tighten clamps.
- Use Pressure Gauge to check fuel pressure.
- Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false readings.

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 idling:
With vacuum hose connected
Approximately 235 kPa (2.4 kg/sq.cm, 34 psi)
With vacuum hose disconnected
Approximately 294 kPa (3.0 kg/sq.cm, 43 psi)

If results are unsatisfactory, perform Fuel Pressure Regulator Check.
