General Precautions

WARNING: This page is about a different car, the 2004 Nissan Quest. 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:
  • Put a "CAUTION: INFLAMMABLE" sign in the work area. 
  • Be sure to work in a well ventilated area and have a CO 2  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: 
    • 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. 
  • 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)  ".
