Bleeding the Fuel System

The fuel system must be bled whenever the fuel tank has been run dry.

Proceed as follows:

The bleeding is automatically performed by a small orifice (A) inside the filter base connected to the overflow valve (B) on injection pump. This system allows air to escape continually through the fuel return line (C) when ignition is ON.

1. Turn key in main switch to the right as far as the first switch position so that the fuel transfer pump is operating.

2. Allow 40 seconds for electronic transfer pump to complete priming.

If engine will not start after this bleeding procedure, continue as follows:

1. Turn key in main switch to the right as far as the first switch position so that the fuel transfer pump is operating.

IMPORTANT: Always use a backup wrench when loosening or tightening fuel lines at nozzles and/or injection pump to avoid damage.

2. Using two open-end wrenches, loosen two fuel line connections at injection nozzles.

3. Crank engine over with starting motor for 15 seconds (but do not start engine) until fuel free from bubbles flows out of loosened connection. Retighten connection to specifications.
