General Precautions

WARNING: This page is about a different car, the 2005 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: When replacing fuel line parts, be sure to observe the following.
CAUTION:
  • Before removing fuel line parts, carry out the following procedures:
  • 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 ignition switch to ON (without starting the engine). Then check for fuel leaks at the fuel tube connections.
    • b) Start the engine and rev the engine, then check for fuel 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.
