Checking Fuel LineINFOID:0000000001327104
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loos
e connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001327105
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 ventila ted 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.
CAUTION:
 Use gasoline required by the regulations for octane number. Refer to GI-5, "
Precaution for Fuel
(Unleaded Premium Gasoline Recommended)".
 Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof containe r and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from th e fuel lines. Refer to EC-87, "
Fuel Pressure Check" (VQ35DE) or EC-
665, "Fuel Pressure Check" (VK45DE).
- Disconnect negative battery terminal.
 Always replace O-ring and clamps with new ones.
 Do not kink or twist tubes when they are being installed.
 Do not tighten hose clamps excessi vely to avoid damaging hoses.
 After connecting fuel tube qu ick connectors, make sure quick
connectors are secure.
Ensure that connector and resin tube do not contact any adja-
cent parts.
 After installing tubes, make su re there is no fuel leakage at
connections in the following steps.
- Apply fuel pressure to fuel li nes with turning ignition switch
“ON” (with engine stopped). Th en check for fuel leaks at con-
nections.
- Start engine and rev it up and check for fuel leaks at connec- tions.
 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 Emi ssion System” parts, refer to
EC-40, "
Description" (VQ35DE) or EC-618, "Description"
(VK45DE).
 For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-46, "
System Description" (VQ35DE) or EC-
624, "System Description" (VK45DE).

REMOVAL
WARNING:
Read “General Precautions” when wo rking on the fuel system. Refer to FL-3, "
General Precaution".
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 main and sub fuel
level sensor units for the top of the fuel is above the main and
sub fuel level sensor units 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-10, "
Component".
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.

665, "Fuel Pressure Check" (VK45DE).
3. Open fuel filler lid.
4. Open filler cap and release the pressure inside fuel tank.
5. Remove rear seat cushion. Refer to SE-95, "
Removal and Installation".
6. Peel off floor carpet, then remove inspection hole cover for main and sub fuel level sensor units by turning clips clockwise by 90
degrees.
7. Disconnect harness connector and fuel feed tube.
Disconnect quick connector as follows: Hold the sides of connector, push in tabs and pull out tube.
 If quick connector sticks to tube of main fuel level sensor unit, push and pull quick connector several times until they start to
move.Then disconnect them by pulling.

 Quick connector can be disconnected when the tabs are
completely depressed. Do not twist it more than neces-
sary.
 Do not use any tools to disconnected quick connector.
 Keep resin tube 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.
 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.
 To keep the connecting porti on clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
8. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows:
CAUTION:
 Do not bend float arm during removal.
 Avoid impacts such as fallin g when handling components.
a. Removal of main fuel level sensor uni t, fuel filter and fuel pump assembly:
i. Remove retainer.
ii. Raise main fuel level sensor unit, fuel filter and fuel pump assembly, and using snap ring pliers, remove fuel hose connec-
tor.
CAUTION:
Be careful not to damage fu el hose connector by expanding
them excessively.
b. Removal of sub fuel level sensor unit:
i. Remove retainer.
ii. Raise and release sub fuel level sensor unit to remove.
