Checking Fuel Lines

ABS0033Z

Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.

General Precautions

ABS00340

WARNING:

When replacing fuel line parts, be sure to observe the following.

●

Put a “CAUTION: INFLAMMABLE” sign in the workshop.

●

Be sure to work in a well ventilated area and furnish workshop with a CO

2

   fire extinguisher. 

●

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.

●

Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.

CAUTION:

●

Before removing fuel line parts, carry out the following procedures:

–

Release fuel pressure from the fuel lines. Refer to 

EC-45, "FUEL PRESSURE RELEASE"

 .

–

Disconnect negative battery terminal. 

●

Always replace O-rings and clamps with new ones.

●

Do not kink or twist tubes when they are being installed.

●

After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.

●

After installing tubes, make sure there is no fuel leakage at
connections in the following steps.

–

Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.

–

Start engine and rev it up and check for fuel leaks at con-
nections.

●

Use only a genuine NISSAN fuel filler cap as a replacement.
If an incorrect fuel filler cap is used, the “MIL” may come
on.

●

For servicing “Evaporative Emission System” parts, refer to

EC-651, "EVAPORATIVE EMISSION SYSTEM"

REMOVAL

WARNING:

Read “General Precautions” before working on the fuel system. Refer to 

FL-3, "General Precautions"

 .

1.

Check fuel level on fuel gauge. If fuel gauge indicates more than
the level as shown in the figure (full or almost full), drain fuel
from fuel tank until fuel gauge indicates level as shown in the fig-
ure or below.
NOTE:
Because fuel will be spilled when removing fuel level sensor unit
for the top of fuel is above the fuel level sensor unit installation
surface. 

●

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 20   (5-1/4 US gal, 4-3/8
Imp gal) of fuel are drained from fuel tank. 

●

In a case that fuel pump does not operate, perform the follow-
ing procedure.

a.

Insert hose of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to draw
fuel from fuel filler tube.

b.

Disconnect fuel filler hose from fuel filler tube. Refer to 

FL-9, "FUEL TANK"

 .

c.

Insert hose into fuel tank through fuel filler hose to draw fuel from fuel tank.

2.

Release the fuel pressure from the fuel lines. Refer to 

EC-45, "FUEL PRESSURE RELEASE"

 .

3.

Open fuel filler lid.

4.

Open fuel filler cap and release the pressure inside fuel tank.

5.

Remove rear seat cushion trim and pad bolts, then lift up rear seat cushion. Refer to 

SE-109, "REAR

●

Do not bend or twist resin tube during installation and
disconnection. 

●

Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.

●

When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one. 

●

Replace same color retainer as before replacing.

●

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
