Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
If the fuel system runs out of fuel or if air is introduced into the fuel system, the system must be primed prior to starting the engine.Before you begin this procedure, check that the following conditions are satisfied:
Ensure that the fuel tanks are filled with clean diesel fuel.
Turn the key switch to the OFF position. Review the following illustrations in order to locate the components for your application. Locate the air purge plug (1), fuel priming pump (2) (if equipped), and the ball valve assembly (3) (if equipped).

Open air purge plug (1) for three full turns. Do not remove this plug.
Illustration 5 g00995967
Ball valve assembly (3a) The valve is in the open position for normal engine operation. (3b) The valve is in the closed position in order to prime the fuel system.
If the fuel system is equipped with a ball valve assembly (3), close the valve (3b) .
Operate the hand priming pump. While you operate the hand priming pump, observe the air purge plug for the presence of fuel.
When a small drop of fuel appears at the threads of the air purge plug, close and tighten the plug.Note: Failure to tighten all fittings could result in serious fuel leaks.
Clean any residual fuel from the engine components.
Continue to operate the fuel priming pump until a strong resistance is felt.
Secure the hand priming pump.
Attempt to start the engine.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Crank the engine for 30 seconds. Allow the starter motor to cool for 2 minutes after each 30 second interval.
Repeat Step 6.a until the engine starts and runs. If the engine runs rough, continue to operate the engine at low idle until the engine runs smoothly.
If the fuel system is equipped with a ball valve assembly that has been closed, allow the engine to operate for 30 seconds and then open the valve (3a) .Note: If the ball valve is left in the closed position for extended periods
