Precaution 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-574, " Fuel Pressure Check " .
- 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 excessi vely to avoid damaging hoses.
• After connecting fuel tube quick connect ors, 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 replacemen t. If an incorrect fuel filler cap is used, the
MIL may come on.
• For servicing “Evaporative Emi ssion System” parts, refer to EC-527 .

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 pro- cedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in di ameter 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 .
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-574, " Fuel Pressure Check " .
4. Remove rear seat bottom. Refer to SE-15 .
5. Turn the four retainers 90 ° in a clockwise direction and remove the fuel pump inspection hole cover.
