CHASSIS INFORMATION
DIPLOMAT 2004
The primary and secondary fuel filters have drains located at the
bottom of the filters. The primary filter has a clear fuel/water
separator bowl located at the bottom of the filter. Water (by weight) is
heavier than fuel and will collect in the separator bowl. Water can
accumulate in the fuel from condensation in the fuel tank or
contamination upon refueling.
The appearance of water in the fuel/separator bowl is easily
identified by the inability of water to mix with the fuel forming small
pools. The water should be drained at the first opportunity. If water
passes through the filters it can cause engine misfire and damage fuel
injectors.
NOTE: Replace both primary and secondary filters
every six months or 15,000 miles.
NOTE: Primary fuel filter is located in the roadside
vented compartment of the motorhome. Secondary fuel
filter is located on curbside of the engine.
To Drain the Filters:
• Shut off the engine.
• Drain the secondary filter first and then the
primary filter.
• Turn the valves counterclockwise approximately 1½ to 2
turns until draining occurs.
• Drain the filters of water and sediment until clear fuel is
visible.
• Turn the valve clockwise to close the drain valves.
• Depending on the amount of contamination it may be
necessary to replace the filters at the first opportunity.
In the event the engine runs out of fuel, the lift pump on the fuel pump
will run for approximately one minute with the ignition on. The ignition may
need to be turned on and off several times before attempting a start. If unable
to restart, contact the nearest
Cummins Center
or phone
1-800-343-7357
for
Cummins Customer Assistance Center.
