FUEL PRESSURE CHECK

Work Procedure

FUEL PRESSURE RELEASE

1.

FUEL PRESSURE RELEASE

1.

Remove fuel pump fuse located in IPDM E/R.

2.

Start engine.

3.

After engine stalls, crank it two or three times to release all fuel pressure.

4.

Turn ignition switch OFF.

5.

Reinstall fuel pump fuse after servicing fuel system.

>> INSPECTION END

FUEL PRESSURE CHECK

1.

FUEL PRESSURE CHECK

CAUTION:

• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• The fuel hose connection method used when taking fuel pressure check must not be used for other

purposes.

• Be careful not to scratch or put debris around connection area when servicing, so that the quick

connector maintains seal ability with O-rings inside.

• Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C,

etc.). Fuel pressure gauge may indicate false readings due to varying engine load and changes in
manifold vacuum.

NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because this models do not have fuel return system.
1.

Release fuel pressure to zero.

2.

Prepare fuel hose for fuel pressure check (B) and fuel tube
adapter [SST: KV10120000] (D), then connect fuel pressure
gauge (A).

CAUTION:

• Use suitable fuel hose for fuel pressure check (genuine

NISSAN fuel hose without quick connector).

• To avoid unnecessary force or tension to hose, use mod-

erately long fuel hose for fuel pressure check.

• Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
• Use Pressure Gauge to check fuel pressure.

3.

Remove fuel hose.

CAUTION:

Do not twist or kink fuel hose because it is plastic hose.

FUEL PRESSURE CHECK

4.

Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.

CAUTION:

• Wipe off oil or dirt from hose insertion part using cloth

moistened 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.

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.

CAUTION:

• Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate

false readings.

• During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK FUEL HOSE AND FUEL TUBE

If result is unsatisfactory, check fuel hoses and fuel tubes for clogging.

Is the inspection result normal?

YES

>> Replace “fuel filter and fuel pump assembly”.

NO

>> Repair or replace.
