쐌 When reconnecting fuel line, always use new clamps.
쐌 Make sure that clamp screw does not contact adjacent
parts.
쐌 Use a torque driver to tighten clamps.
쐌 Use Pressure Gauge to check fuel pressure.
쐌 Do not perform fuel pressure check with system operat-
ing. Fuel pressure gauge may indicate false readings.
1. Release fuel pressure to zero.
2. Disconnect fuel hose between fuel filter and fuel tube (engine
side)..
3. Install fuel pressure gauge between the fuel filter and fuel
tube..
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
