Bleeding the Fuel System

Bleed air from the fuel system to prevent starting failures

and/or erratic operation. One or more of the following

causes air to collect in the fuel system:

Operating the generator set until it runs out of fuel.

Developing air leaks in the plumbing between the fuel

tank and the engine-mounted fuel pump.

Replacing the fuel filter.

Note: If the ADC 2100 indicates an overcrank fault

during this procedure, disconnect the negative

wire from the fuel solenoid (allowing the fuel

injection pump to fill with fuel) and repeat this

procedure after allowing the starter motor to cool

down.

Note: Have a rag handy during the bleeding procedure.

Wipe up all spilled diesel fuel after bleeding the

system. Wash hands after any contact with fuel oil.

Note: Do not crank the engine to prime the fuel system.

Use the following procedure.
