CAUTION:
  • Use gasoline required by the regulations for octane number. Refer to FUEL .
  • Before removing fuel line parts, perform out the following procedures:
    1. Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in safe area.
    2. Release fuel pressure from the fuel lines. Refer to REMOVAL AND INSTALLATION .
    3. Disconnect the battery cable from the negative terminal.
  • Always replace O-ring and clamps with new ones.
  • Never kink or twist tubes when they are being installed.
  • Never tighten hose clamps excessively to avoid damaging hoses.
  • After installing tubes, check there is no fuel leakage at connections in the following steps.
    • Apply fuel pressure to fuel lines with turning ignition switch "ON" (with engine stopped). Then check for fuel leakage at connections.
