Checking Fuel Lines
Inspect fuel lines, fuel filler cap and fuel tank for improper attachment, leaks, cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace damaged parts.
General Precautions
WARNING:
When replacing fuel line part s, 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 CO2 fire extinguisher.
● Do not smoke whi l e ser v ic ing fu el syst e m. Ke ep op e n fl a mes and sparks aw ay f rom t he wo rk a r ea.
CAUTION:
● Before removing fuel line parts, carry out the following procedures:
– Put drained fuel in an e xpl osi on-p roof c ontainer and put the lid on securely. Keep the container in
safe area.
– Release fuel pressure from the fuel lines. Refer to EC-46, "FUEL PRESSURE RELEASE" .
– Disconnect the battery negative terminal.
● Always replace O-rings and clamps with new ones.
● Do not kink or twist hoses when they are being installed.
● Do not tighten hose clamps excessively to avoid damaging hoses.
Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specification s are the s ame for al l ru bber
hose clamps.
Ensure that screw does not contact adjacent parts.

the quick connectors are secure.
Ensure that the 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 stop pe d). The n c he ck for fue l l eaks a t co nnections.
– Start the engine and rev it up and check for fuel leaks at
connections.
● 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 servici ng “E vapora ti ve Emis sio n Syst em” p ar t s, refe r to

REMOVAL
WARNING:
Follow the “Genera l Precautio ns” befor e working o n the f uel syste m. Refer to FL-3, "
tions" .
1. Remove the fuel filler cap to release the pressure from inside the fuel tank.
2. Check the fuel level on level gauge. If the fuel gauge indicates
more than the level as shown (full or almost full), drain the fuel
from the fuel tank until the fuel gauge indicates the level as
shown, or less.
● If the fuel pump does not operate, use the following procedure
to drain the fuel to the specified level.
a. Insert a suitable hose of less than 15 mm (0.59 in) diameter into
the fuel filler pipe through the fue l filler o pening to drain the fue l
from fuel filler pipe.
b. Remove the LH rear wheel and tire. Refer to WT-6, "
Rotation" .
c. Disconnect the fuel filler hose from the fuel filler pipe.
General Precau-
WBIA0390E

d. Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.
● As a guide , the fuel level reaches th e fuel gauge position as shown, or less, when appro ximately 14
liters (3 3/4 U S gal, 3 1/8 Imp gal) of fuel are drained from the fuel tank when it is full.
3. Release the fuel pressure from the fuel lines. Refer to EC-46, "
FUEL PRESSURE RELEASE" .
4. Remove the three nuts and remove fuel line pump protector.
5. Disconnect the EVAP hose at the EVAP canister.

Disconnect the quick connector as follows:
● Hold the si des of the conn ector, push in tabs and pull out the
tube.
● If the connector and the tube are stuck together, push and pull
several times un til they start to mov e. Then discon nect them
by pulling.
CAUTION:
● The quic k connector can b e disconnec ted when the tabs
are completely depressed. Do not twist the quick connector more than necessary.
● Do not use any tools to disconnect the quick connector.
● Keep the resin tube away from heat. Be especially careful
when welding near the tube.
● Prevent any acid liquids such as battery electrolyte, from
getting on the resin tube.
● Do not bend or twist the resin tube during connection.
● Do not remove the remaining retainer on the hard tube (or
the equivalent) except when the resin tube or the retainer
is replaced.
● When the resin tube or hard tube, or the equivalent, is
replaced, also replace the retainer with a new one (white
colored retainer).
