Priming If The Engine Has Run
Out Of Fuel
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure
fuel spray can cause serious injury or
death.
1. Add a substantial amount of fuel to the
tank, approximately 2 to 5 gal (8L to
19L).
2. Turn ignition switch to the start position to
engage starter for one second, return ig-
nition switch to run position. This will
activate in tank fuel pump for approxi-
mately 15 seconds. Repeat this process
twice.
3. Start the engine using the “Normal Start-
ing” procedure. Refer to “Starting Proce-
dures” in “Starting and Operating” for
further information.
CAUTION!
Do not engage the starter motor for more
than 15 seconds at a time. Allow two
minutes between the cranking intervals.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system.
NOTE:
• A maximum blend of 5% biodiesel, meet-
ing ASTM specification D-975 may be used
with your Cummins diesel engine. (Chassis
Cab models not configured with B20 capa-
bility.)
• A maximum blend of 20% biodiesel, meet-
ing ASTM specification D-7467 may be
used with your Cummins diesel engine.
(Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20%
can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or
approved for use with your Cummins diesel
engine.
• In addition, commercially available fuel ad-
ditives are not necessary for the proper
operation of your Cummins diesel engine.
