Fuel Filters
The fuel filters are located on the curbside frame rail,
next to the engine. The primary fuel filter has a drain and
a clear sediment bowl, located at the bottom of the filter.
Water (by weight) is heavier than fuel and will collect in
the sediment bowl. Water can accumulate in the fuel from
condensation in the fuel tank or contamination upon refuel-
ing.
The appearance of water in the sediment 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.
Shut off the engine and open the drain valve. Turn the
valve counterclockwise approximately 1½ to 2 turns until
draining occurs. Drain the fuel/water separator of water
and sediment until clear fuel is visible. Turn the valve
clockwise to close the drain valve.
NOTE:
Replace the primary filter every six months or 11,000 miles. Refer to the engine
OEM manual for Secondary filter replacement intervals.
NOTE:
When draining or changing the fuel filters, always use a container. Dispose of the
container properly. The water and sediment can contain petroleum products.
Consult the local waste disposal agency for recommended disposal guidelines
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 have to be turned on and off several times before attempt-
ing a start. If unable to restart, contact the nearest Cummins Center or phone 1-800-343-7357 for
Cummins Customer Assistance.
HYDRAULIC SYSTEM
On a walk around and pre-check of the motorhome, look for oil leaks under the coach and around
hose fittings. If a hose connection appears to be leaking, clean the filter and the surrounding area. If
seepage continues, have the problem corrected to prevent an untimely failure.
