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-35, "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

ECH-121, "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

“MI” may come on.

WARNING:

Read “General Precautions” when working on the fuel system. Refer to

FL-3, "General Precautions"

REMOVAL

Release the fuel pressure from the fuel lines. Refer to

ECH-121, "Work Procedure"

Check fuel level on a level ground. If the fuel level is at 1/2 or higher, drain enough fuel so that the level on
the fuel gauge is at half or below.
• This is to prevent overflow of fuel from the tank when the fuel level sensor unit, fuel filter and fuel pump

assembly is removed

• In the event of malfunction in fuel pump, insert a hose measuring less than 20mm (0.79 in) in diameter

into fuel filler tube through fuel filler opening to draw fuel from filler tube.

- Disconnect fuel filler hose from fuel filler tube. Refer to

FL-10, "Exploded View"

- Insert hose into fuel tank through fuel filler hose to draw fuel from fuel tank.

Disconnect batterie cable from negative terminal.

• Remove quick connector in the following procedures.
- NOTE:

• The figure show the process of quick connector disconnection. Parts arround quick connector could

have a different shape compare to the figure.

- Hold the sides of quick connector, press tabs and pull out fuel

feed tube.

- If quick connector sticks to tube of main fuel level sensor unit,

push and pull quick connectors several times until they start to
move. Then disconnect them by pulling.

CAUTION:

• Quick connector can be disconnected when the tabs are

depressed completely. Never twist it more than neces-
sary.

• Never 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.

• Never bend or twist resin tube during installation and dis-

connection.

• Never insert plug, preventing damage to O–ring in quick

connector.

• To keep the connecting portion clean and to avoid dam-

age and foreign materials, cover them completely with
plastic bags or something similar.
