ON BOARD REFUELING VAPOR RECOVERY (ORVR)PFP:00032
System DescriptionUBS00QBC
From the beginning of refueling, the air and vapor inside the fuel tank go through refueling EVAP vapor cut
valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is
released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and
refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged
during driving.
WAR NIN G:
When conducting inspections below, be sure to observe the following:
Put a “CAUTION: FLAMMABLE” sign in workshop.
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
Be sure to furnish the workshop with a CO2 fire extinguisher.
CAUTION:
Before removing fuel line parts, carry out the following procedures:
–Put drained fuel in an explosion-proof container and put lid on securely.
–Release fuel pressure from fuel line. Refer to EC-81, "FUEL PRESSURE RELEASE" .
–Disconnect negative battery cable.
Always replace O-ring when the fuel gauge retainer is removed.
Do not kink or twist hose and tube when they are installed.
Do not tighten hose and clamps excessively to avoid damaging hoses.
After installation, run engine and check for fuel leaks at connection.
Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.

Component InspectionUBS00QBE
REFUELING EVAP VAPOR CUT VALVE
With CONSULT-II
1. Remove fuel tank. Refer to FL-9, "FUEL TANK" .
2. Drain fuel from the tank as follows:
a. Remove fuel feed hose located on the fuel gauge retainer.
b. Connect a spare fuel hose, one side to fuel gauge retainer where the hose was removed and the other
side to a fuel container.
c. Drain fuel using “FUEL PUMP RELAY” in “ACTIVE TEST” mode with CONSULT-II.
3. Check refueling EVAP vapor cut valve for being stuck to close as follows.
Blow air into the refueling EVAP vapor cut valve (from the end of EVAP/ORVR line hose), and check that
the air flows freely into the tank.
4. Check refueling EVAP vapor cut valve for being stuck to open as follows.
a. Connect vacuum pump to hose end.
b. Remove fuel gauge retainer with fuel gauge unit.
Always replace O-ring with new one.
c. Put fuel tank upside down.
d. Apply vacuum pressure to hose end [−13.3 kPa (−100 mmHg, −3.94 inHg)] with fuel gauge retainer
remaining open and check that the pressure is applicable.
1. Filler tube 2. Recirculation line 3. EVAP/ORVR line
4. Vacuum/pressure handy pump 5. Fuel tank

Fuel Pressure CheckUBS00QOB
FUEL PRESSURE RELEASE
With CONSULT-II
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel
pressure.
5. Turn ignition switch OFF.
Without CONSULT-II
1. Remove fuel pump fuse (1) located in IPDM E/R (2).
: Vehicle front
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.
FUEL PRESSURE CHECK
CAUTION:
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because C11 models do not have fuel return system.
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 sealability 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.
1. Release fuel pressure to zero. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.
: To quick connector
: To fuel tube (engine side)
C: Clamp
Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "
INTAKE MANIFOLD" .

BASIC SERVICE PROCEDURE
2007 Versa
Do not twist or kink fuel hose because it is plastic hose.
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.
12. 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.
13. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure
to zero. Refer to EC-81, "
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 (3.5 bar, 3.57 kg/cm
2 , 51 psi)
