• Check for complete insertion of
motor mount. Replace as
necessary.
• New leg to mount flange head bolts
should be torqued to 210-230 lb-ft
(284-311 Nm).
Fuel System
Important information on your vehicle's fuel
system.
Location of Fuel Shut-off Valves
Fuel shut-off valves for the fuel crossover
line are on the bottom of the secondary
fuel tank, at the crossover line connection.
They are optional on the primary fuel tank.
Specification
Use only diesel fuel as recommended by
engine manufacturers.
WARNING!
Diesel fuel in the presence of an ignition
source could cause an explosion. A mixture
of gasoline or alcohol with diesel fuel in-
creases this risk of explosion. Do not re-
move a fuel tank cap near an open flame.
Use only the fuel and/or additives recom-
mended for your engine. Failure to comply
may result in death, personal injury, equip-
ment or property damage.
CAUTION
If anyone ever pours gasoline into your fuel
tank, drain the entire system. Otherwise, the
pump and engine will be damaged. Don’t try
to dilute the gasoline by adding diesel fuel
(See Warning above).

Manual provided with this chassis.
Frame
WARNING!
Do not cut, splice or weld frame rails or drill
through the top or bottom flanges of the
rails. These operations could affect frame
rail strength leading to a failure resulting in
an accident. Rail failures resulting from such
modifications are not warrantable. Failure to
comply may result in death, personal injury,
equipment or property damage.
WARNING!
Frame welding is NOT recommended. The
high heat of welding nullifies the special
heat treatment of the rails, greatly reducing
the tensile strength of the frame rail. If a
frame member becomes cracked from over-
loading, fatigue, surface damage or a colli-
sion, the only permanent repair is to replace
the damaged frame member with a new
part.
Emergency Welding
In an emergency, a temporary repair may
be performed. Observe the following
precautions to protect electronic systems
during welding operations. Emergency
welding procedures are further explained in
the maintenance manuals. Please refer to
the ordering information on the back cover
to obtain a maintenance manual.
In the event of emergency welding of a
frame rail and when welding any other part
of your truck or any component attached to
your truck, observe the following
precautions before welding:
