General PrecautionsINFOID:0000000003793245
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the workshop.
Be sure to work in a well ventilated area and furnish workshop with a CO
2 fire extinguisher.
Never smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-29, "
Fuel".
Before removing fuel line parts, perform out the following procedures:
- Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from the fuel lines. Refer to EC-411, "
Inspection".
- Disconnect the battery cable from the negative terminal.
Always replace O-ring and clamps with new ones.
Never kink or twist tubes when they are being installed.
Never tighten hose clamps excessively to avoid damaging hoses.
After installing tubes, check 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 leakage at connections.
- Start engine and rev it up and check for fuel leakage at connections.
Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
“MI” may come on.
For servicing “Evaporative Emission System” parts, refer to EC-76, "
System Diagram".

WARNING:
Read “General Precautions” when working on the fuel system. Refer to FL-2, "
General Precautions".
REMOVAL
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
units for the top of the fuel is above the fuel level sensor units
installation surface.
• As a guide, fuel level becomes the position as shown in the
figure or below when approximately 10 (2-1/4 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, "Exploded View".
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-411, "
Inspection".
3. Open fuel filler lid.
4. Open filler cap and release the pressure inside fuel tank.
5. Remove rear seat cushion. Refer to SE-98, "
Exploded View" (WITH VENTILATION SEAT) or SE-140,
"Exploded View" (WITHOUT VENTILATION SEAT).
6. Peel off floor carpet, then remove inspection hole cover units by
turning clips clockwise by 90 degrees.
7. Disconnect harness connector and quick connector.
Disconnect quick connector as follows:
Hold the sides of connector, push in tabs (B) and pull out fuel
feed tube.
If quick connector sticks to tube of fuel level sensor unit, push
and pull quick connector several times until they start to move.
Then disconnect them by pulling.

Quick connector (1) can be disconnected when the tabs
(F) are completely depressed. Never twist it more than
necessary.
Never use any tools to disconnected quick connector.
Keep resin tube (C) away from heat. Be especially careful
when welding near the resin tube.
Prevent acid liquid such as battery electrolyte, etc. from
getting on resin tube.
Never bend or twist resin tube during installation and dis-
connection.
Never remove the remaining retainer (2) on hard tube (or
the equivalent) (A) 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.
To keep the connecting portion clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags (A) or something similar.
8. Remove lock ring for fuel level sensor unit, fuel filter and fuel
pump assembly with fuel tank lock ring wrench (commercial ser-
vice tool) by turning counterclockwise.
9. Remove fuel level sensor unit, fuel filter and fuel pump assembly
(1).
Never bend float arm during removal.
Never pollute the inside by residue fuel. Draw out avoiding
inclination by supporting with a cloth.
Never cause impacts such by dropping when handling compo-
nents.
