Fuel Supply Module (FSM) Priming Procedure using a Fuel Pressure Gauge

1. Verify the engine is in a level vertical position. 2. Verify the vessel fuel supply line is connected to the outboard fuel system inlet fitting. 3. Connect a fuel pressure gauge to the fuel rail Schrader valve. WARNING: The fuel supply module (FSM) is not vented to ambient air. Excessive key-on events to prime a dry or drained fuel system may damage the fuel pumps. Use this purge tool method instead.
