DRAINING THE FUEL FILTER
WATER TRAP - DIESEL
WARNING:
Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage.
WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle has a diesel fuel conditioner
module. The module is mounted between
the outboard side of the fuel tank and the
frame rail.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
You should drain water from the
module assembly whenever the
warning light illuminates or a
message appears in the information
display advising you to drain the water
separator. This occurs when approximately
6.76 fl oz (200 ml) of water accumulates
in the module. If you allow the water level
to exceed this level, the water may pass
through to the engine and may cause fuel
injection equipment damage.
