WARNING: When replacing fuel line parts, be sure to observe the following:
  • Put a "CAUTION: INFLAMMABLE" sign in the work area.
  • Be sure to work in a well ventilated area and have a CO2 fire extinguisher.
  • Do not smoke while working on the fuel system. Keep open flames and sparks away from the work area.
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.
  • 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.

  • After installing the tubes, run the engine and check for fuel leaks at the connections using the following steps:
    1. 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.
    2. Start the engine and rev the engine, then check for fuel leaks at the fuel tube 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) ".
