• Always replace O-rings 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.
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
• After connecting the fuel tube quick connectors, make sure
the quick connectors are secure.
Check that the connector and resin tube do not contact any
adjacent parts.
- a) Apply fuel pressure to the fuel system by turning the igni-
tion switch to ON (without starting the engine). Then check for
fuel leaks at the fuel tube connections.

leaks at the fuel tube connections.
• After installing the tubes, run the engine and check for fuel
leaks at the 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.

depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid liquid such as battery electrolyte, etc. from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor,
fuel filter, and fuel pump assembly.
• When the tube or fuel level sensor, fuel filter, and fuel pump assembly is replaced, also replace
the retainer with a new one (green colored retainer).
