FUEL PRESSURE
4. Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.
• No.2 spool (5)
• Wipe off oil or dirt from hose insertion part using cloth moist-ened with gasoline.
• Apply proper amount of gasoline between top of the fuel tube
(3) and No.1 spool (4).
• Insert fuel hose for fuel pressure check until it touches the No.1 spool on fuel tube.
• Use NISSAN genuine hose clamp (part number: 16439 N4710 or 16439 40U00).
• When reconnecting fuel line, always use new clamps.
• Use a torque driver to tighten clamps.
• Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08 in).
• Make sure that clamp screw does not contact adjacent parts.
5. Connect fuel tube adapter to quick connector. • A: Fuel pressure gauge
• B: Fuel hose for fuel pressure check
6. After connecting fuel hose for fuel pressure check, pull the hose with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
7. Turn ignition switch ON and check for fuel leakage.
8. Start engine and check for fuel leakage.
9. Read the indication of fuel pressure gauge. • Do not perform fuel pressure check with system operating.
Fuel pressure gauge may indicate false readings.
• During fuel pressure check, confirm for f uel leakage from fuel connection every 3 minutes.
10. If result is unsatisfactory, go to next step.
11. Check the following. • Fuel hoses and fuel tubes for clogging
• Fuel filter for clogging
• Fuel pump
• Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator. Refer to FL-6, "
Removal and Installation".
If NG, repair or replace.
12. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".Tightening torque: 1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling: Approximately 350 kPa (3.57 kg/cm
2, 51 psi)

conditions (such as when engine oil temperature does not rise enough since a journey distance is too
short during winter). The symptom will not be detect ed after changing engine oil or changing driving con-
dition.
