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 fuel 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.
If NG, repair or replace.

Inspection

INFOID:0000000001161422

1.

Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.

2.

Check EVAP canister as follows:

a.

Block port (B). Orally blow air through port (A).
Check that air flows freely through port (C).

b.

Block port (A). Orally blow air through port (B).
Check that air flows freely through port (C).

3.

Visually inspect the fuel check valve for cracks, damage, loose connections chafing and deterioration. 

4.

Check fuel check valve as follows:

a.

Blow air through connector on the fuel tank side. A considerable
resistance should be felt and a portion of air flow should be
directed toward the EVAP canister side.

b.

Blow air through connector on EVAP canister side. Air flow
should be smoothly directed toward fuel tank side.

c.

If fuel check valve is suspected or not properly functioning in
step 1 and 2 above, replace it.

5.

Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.

a.

Wipe clean valve housing.

b.

Check valve opening pressure and vacuum.

c.

If out of specification, replace fuel filler cap as an assembly.
