Refer to Operation and Maintenance Manual, "General Hazard Information and High Pressure Fuel Lines" before adjustments and repairs are performed.Note: Refer to Systems Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.Ensure that all adjustments and repairs are performed by authorized personnel that have had the correct training.
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.
If air enters the fuel system, the air must be purged from the fuel system before the engine can be started. Air can enter the fuel system when the following events occur:
The fuel tank is empty or the fuel tank has been partially drained.
The low-pressure fuel lines are disconnected.
A leak exists in the low-pressure fuel system.
The fuel filter has been replaced.
The engine has not been in use for an extended period.Hand Fuel Priming Pump
DO NOT loosen the high-pressure fuel lines in order to purge air from the fuel system. This procedure is not required.Use the following procedures in order to remove air from the fuel system:
Ensure that the fuel system is in working order to remove air from the fuel system. Ensure that the primary filter is clean and free from dirt.
Check that the fuel supply valve (if equipped) is in the ON position.
Illustration 1 g03352705
Unlock priming pump handle (1) by turning handle counterclockwise. Note: During priming the hand pressure required to prime the fuel system will increase.
Operate the hand priming pump, the fuel system will require approximately 200 depression of the pump before the system will be primed. Lock and priming handle by securing the handle into pump body (2). Push handle in and turn handle clockwise to lock. Note: Ensure priming handle (1) is locked correctly into place . If the priming handle is not locked into place, fuel flow to the fuel system will be obstructed.
If the engine will not start, repeat steps 2 to step 4
Refer to the Operation and Maintenance Manual, "Starting the Engine or Cold Weather Starting" for information on starting the engine. After the engine has stopped, you must wait for 10 minutes in order to allow the fuel pressure to be purged from the high-pressure fuel lines before any service or repair is performed on the engine fuel lines. If necessary, perform minor adjustments. Repair any leaks from the low-pressure fuel system and from the cooling, lubrication, or air systems. Replace any high-pressure fuel line that has leaked. Refer to Disassembly and Assembly, "Fuel Injection Lines - Install".If you inspect the engine in operation, always use the proper inspection procedure in order to avoid a fluid penetration hazard. Refer to Operation and Maintenance Manual, "General hazard Information".
The low-pressure fuel system can be pressurized for a time period after the engine has stopped operating. The operating pressure of the low-pressure fuel system can be 500 kPa (73 psi). The secondary fuel filters should be drained before any maintenance of the low-pressure fuel system is carried out.
If the engine will not start, refer to Troubleshooting, "Engine Cranks but will not Start".Electric Prime
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.
DO NOT loosen the high-pressure fuel lines in order to purge air from the fuel system. This procedure is not required.The electric priming pump only operates during the priming of the fuel system, during engine operation the electric priming pump is turned off.
Ensure that the fuel system is in working order. Check that the fuel supply valve (if equipped) is in the ON position.

Typical example
Ensure that the battery disconnect switch is in the ON position. Ensure that the keyswitch is in the OFF position.
Remove the protection cap (1). Depress valve (2) in order to purge air. Caterpillar recommend that a tire inflator with a suitable length of clear hose attached to be used. Refer to illustration 3.
Illustration 3 g02948436
(A) Connection for clear hose
(B) Inflator Note: The electric priming pump will only operate with the keyswitch in the OFF position.
With tool (B) installed to valve (2) press button (4) and keep the button depressed. The button will illuminate and the priming pump will start to operate.
When fuel has filled the bowl at the bottom of the filter (3), the tool (B) can be removed. Ensure that the protection cap (1) is install. The electric priming pump will stop once the button is released.
Press again the button (4) and keep the button depressed for approximately 2 minutes. After the 2 minutes, the fuel system will be primed and the engine is ready to start.
Start the engine, refer to this Operation and Maintenance Manual, "Starting the Engine or Cold Weather Starting" for more information.
If the engine will not start repeat step 6 to step 7. Ensure that the keyswitch is in the OFF position during fuel system prime.
After the engine has stopped, you must wait for 10 minutes in order to allow the fuel pressure to be purged from the high-pressure fuel lines before any service or repair is performed on the engine fuel lines.
