WARNING
Fuel is flammable and explosive. Ensure that the key switch is off and the lanyard is positioned so that the engine cannot start.
Do not smoke or allow sources of spark or open flame in the area while servicing. Keep the work area well ventilated and avoid
prolonged exposure to vapors. Always check for leaks before attempting to start the engine, and wipe up any spilled fuel
immediately.
1. If you suspect the fuel rails or a component of the fuel delivery system (electronic fuel pumps, VST, fuel lines, fuel rails, air
system), connect a dual pressure, liquid‑filled gauge to the port and starboard fuel rails and check both air and fuel pressure
together.
2. If fuel and air pressures are out of specification, refer to the following chart for help with system diagnostics.
3. Refer to Electric Fuel Pump Pressure Tests and Air Compressor Pressure Test for procedures on checking the fuel and
air system pressure.
