 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

.

• Before removing fuel line parts, carry 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-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 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 adja-
cent 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 stopped). Then 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 Emission System” parts, refer to

EC-40, "Description"
