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

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-28, "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-141, "Work Procedure"

- 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

“MIL” may come on.

• For servicing “On Board Refueling Vapor Recovery (ORVR)” parts, refer to

EC-58, "Diagnosis

Precautions for Removing Battery Terminal

INFOID:0000000009962128

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.
