Priming If The Engine Has Run Out Of
Fuel
1. Add a substantial amount of fuel to the
tank, approximately 2 to 5 gal (8L to
19L).
2. Two priming cycles must be completed.
Turn ignition switch to the run position.
This will activate the in tank fuel pump
for approximately 30 seconds. Turn igni
-
tion switch to the off position, and leave
off for at least 5 seconds. Turn ignition
switch to the run position to complete an
additional priming cycle and activate the
in tank fuel pump for approximately 30
seconds.
3. Start the engine using the “Normal
Starting” procedure. Refer to “Starting
Procedures” in “Starting and Operating”
for further information.
4. Once the engine starts, allow the engine
to idle for a minimum of 30 seconds.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
NOTE:
A maximum blend of 5% biodiesel,
meeting ASTM specification D-975 may
be used with your Cummins diesel engine.
(Chassis Cab models not configured with
B20 capability.)
A maximum blend of 20% biodiesel,
meeting 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
ability 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
additives are not necessary for the proper
operation of your Cummins diesel engine.
HOISTING
A conventional floor jack may be used at the
jacking locations. Refer to the graphics that
show jacking locations. However, a floor jack
or frame hoist must never be used on any
other parts of the underbody.
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.
CAUTION!
Do not engage the starter motor for more
than 15 seconds at a time. Allow two
minutes between the cranking intervals.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable
under 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.
