Filling the Fuel System

When starting an engine for the first time, or starting an engine that ran out of fuel or was drained of fuel,
fill and prime the fuel system.
To fill and prime the fuel system:
1. Squeeze the fuel line primer bulb until it feels firm.
2. Turn the key switch to the "ON" position for three seconds. This operates the electric fuel pump.
3. Turn the key switch back to the "OFF" position and squeeze the primer bulb again until it feels
firm.
4. Turn the key switch to the "ON" position again for three seconds.
5. Continue this procedure until the fuel line primer bulb stays firm.
