Priming the Fuel System - KM63 GEN2 - Two-Filter System
While servicing the fuel system, air can enter the system and will need to be purged. If the air in the system is not properly purged, a no-start condition, longer than normal crank times, or electronic service codes related to unstable rail pressure, may occur. If a service code is set after work is performed on the fuel system, clear the codes and retest the system. The KM63 GEN2 fuel system requires higher priming pressures than previous fuel systems; it is important that only Detroit® approved priming tools are used. The use of other priming tools may not properly prime the lubrication circuit on the high pressure fuel pump, leading to severe damage to the pump and/or other fuel system components. See Figure 1 for location of the High Pressure (HP) flange. See Figures 2 and 3 for identification purposes.

2 Priming the Fuel System - KM63 GEN2 - Two-Filter System • DAVCO Shop Pro FXP 95 • ESOC ® 250E Prime as follows: 1. Connect the Detroit® approved priming tool. Refer to the Original Equipment Manufacturer (OEM) instructions provided with the tool. NOTE: If there is a need to stop the machine for any reason (leaks, forgot to connect hose, etc.), depress the STOP button. 2. Turn the priming tool ON. 3. Prime the fuel system for TWO (2) minutes. WARNING: ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.
WARNING: PERSONAL INJURY To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked. 4. With the priming tool still CONNECTED and PRIMING, start the engine and run at idle (600 rpm) for ONE (1) minute. 5. Turn the priming tool OFF and close the ball valve. 6. Increase engine speed to 1500 rpm for ONE (1) additional minute. 7. Reduce engine speed to idle (600 rpm). 8. Disconnect the priming tool. Refer to OEM instructions. NOTE: Starting difficulty may occur until a drive cycle has been completed to completely remove all remaining air from the fuel system. 9. Take the unit for a 15-minute road test to purge all remaining air from the fuel system.

If a service code is set after work is performed on the fuel system, clear the codes and retest the system. The KM59 GEN1 fuel system requires specific priming pressures to properly prime the lubrication circuit on the high pressure pump. To prevent severe damage to the pump and/or other fuel system components, it is important that only a Detroit ® approved priming tool is used. See Figure 1 for location of the high pressure flange.
