General Precautions

WARNING: This page is about a different car, the 2008 Nissan Maxima. 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:
    • 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 "FUEL PRESSURE RELEASE ".
    • Disconnect the battery ground cable.
  • 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.

    Ensure that the connector and resin tube do not contact any adjacent parts.

    • a) Apply fuel pressure to the fuel lines 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 tubes, run engine and check for fuel leaks 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 "Evaporative Emission System" parts, refer to "EVAPORATIVE EMISSION SYSTEM ".
  • For servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to "ON BOARD REFUELING VAPOR RECOVERY (ORVR) ".
