WARNING: When replacing the fuel line parts, observe the following:
  • Place a "CAUTION: INFLAMMABLE" sign in the workshop.
  • Do not smoke while servicing the fuel system. Keep open flames and sparks away from the work area.
  • Have a CO2 fire extinguisher in the workshop. 
CAUTION:
  • Before removing the fuel line parts, use the following procedures:
    • Store the drained fuel in an explosion-proof container and put the lid on securely.
    • Release the fuel pressure from the fuel system. Refer to FUEL PRESSURE RELEASE (QG18DE) and FUEL PRESSURE RELEASE (QR25DE).
    • Disconnect the battery ground cable.
  • Always replace the O-ring seals with new ones.
  • Do not kink or twist any of the hoses and tubes during removal and installation.
  • Do not over tighten the hose clamps to avoid damaging the hoses.
  • After installation, run the engine and check for fuel leaks at the connections.
