Checking Fuel LinesEBS00TSF
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 PrecautionsEBS00TSG
WAR NIN G:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the work area.
Be sure to work in a well ventilated area and have a CO2 fire extinguisher.
Do not smoke while working on the 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:
Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Regular Gasoline Recommended)" .
Before removing fuel line parts, perform the following procedures:
–Release fuel pressure from the fuel lines. Refer to EC-81, "FUEL PRESSURE RELEASE" .
–Disconnect the battery ground cable.
Always replace O-rings and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Perform work on level surface.
Do not tighten hose clamps excessively to avoid damaging hoses.
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 by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
–Start 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 servicing “Evaporative Emission System” parts, refer to EC-31, "EVAPORATIVE EMISSION
SYSTEM" .
For servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to EC-38, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" .

WA RN ING:
Be sure to read “General Precautions” before working on the fuel system. Refer to FL-4, "
General Pre-
cautions" .
1. Check fuel level with the vehicle on a level surface. If the fuel
gauge indicates more than the level as shown (7/8 full), drain
fuel from the fuel tank until the fuel gauge indicates level as
shown (7/8 full).
NOTE:
Fuel will be spilled when removing fuel pump assembly if fuel
level is above the fuel pump assembly installation surface.
As a guide, fuel level is at the level as shown or below when
approximately 12 (3 1/8 US gal, 2 5/8 Imp gal) of fuel is
drained from a full fuel tank.
In case fuel pump does not operate, perform the following
procedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
drain fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-9, "
FUEL TANK" .
c. Insert fuel tubing into fuel tank through fuel filler hose to drain fuel from fuel tank.
2. Open fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
3. Release the fuel pressure from the fuel lines. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
4. Remove rear seat bottom. Refer to SE-14, "
REAR SEAT" .
5. Turn the four retainers 90° in a clockwise direction and remove the fuel pump inspection hole cover.
