Fuel/Water separator is located in rear engine compartment on left and right
of frame. If “water in fuel” light is illuminated, fuel filter will need to be
drained. Shut off engine and open drain valve. Turn valve counterclockwise
approximately 1-1/2 to 2 turns until draining occurs. Drain fuel/water separator
of water and sediment until clear fuel is visible. Turn valve clockwise to close
drain valve.
In the event the ISC engine runs out of fuel, the lift pump on the fuel pump
will run for approximately 1 minute with the ignition ON. The ignition may have
to be turned on and off several times before attempting a start. If unable to
restart, contact the nearest Cummins Center or phone 1-800-DIESELS for
Cummins Customer Assistance Center.
Operation/Restart After Running Out Of Fuel
• Turn the ignition switch to the ON position.
• The green power light on the control panel should illuminate.
• Remove the cap from the Schrader air valve and press and release the “AIR
PURGE” switch on control panel. The yellow “AIR PURGE” lamp will
illuminate. Depress and hold the Schrader air valve open to release the
excess air from the system. The electronics will maintain the pump opera-
tion for 50-60 seconds. Recycle the pump and when the fuel is observed
from the Schrader valve, release (so the fuel no longer leaks from it).
• The internal pump will continue to run, pressurizing the fuel system while
forcing fuel through the fuel lines.
• It may require recycling the “AIR PURGE” about 6 times before pulling
enough fuel from the tank to filter.
