WARNING
When removing the fuel filter, a quanti-
ty of fuel will escape. DO NOT smoke
or allow an open flame in close prox-
imity. Failure to do so could ignite a
fire or cause an explosion which could
result in serious injury to you and/or
bystanders. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
CAUTION
Replace fuel filters with parts of the
same part number. PACCAR periodi-
cally changes its filter design, and fil-
ters of different part numbers are not
interchangeable. Use of incorrect filter
part numbers or non-genuine filters
can result in low pressure fuel fault co-
des and/or severe engine damage.
Contact a Kenworth or Peterbilt dealer
to verify the correct fuel filter part num-
bers.
NOTE
The fuel filter and the hand pump are
located on the left-hand side of the en-
gine, as viewed from the driver's seat.
