2. Release fuel pressure from the fuel lines. Refer to FUEL PRESSURE CHECK .
3. Disconnect the battery negative terminal.
Always replace O-rings and clamps with new ones.
Do not kink or twist hoses when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.

After installing tubes, make sure 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 leaks at connections.
